    It does not work for me at all :( I am using LMDE which is with Cinnamon 2.0.14. I downloaded version 2.1 and unzip it in ~/.local/share/cinnamon/applets Then I disable the Window list Then I enable the Window list with window preview Then I restarted cinnamon with alt-F2 and r I have no program in the task bar / window list ! Do you know why it does not work ? Thank you a lot for your help

    Wonderful Applet, simple expansion on the original design. Seems to work well, and is very convenient!

    Hi, thanks for the applet, I use it all the time. I'd like to ask you whether it is possible to support Chrome Apps better. I am using Hangouts app along with the google-chrome. While technically it is the same application, your window list treats them as such and groups them / uses the same icon for them. However it actually has different WMClass, therefore it should be treated as different application. Can be seen on the screenshot:

    I made also a little patch with these Improvements: (1) You can now set the size of the Preview with the settingsmanager included in cinnamon (2) A little styling for cinnomon 2.0; The styling is harcoded, to edit the styling go to line 80 I've uploaded it as a zip on dropbox:

    Here's a patch for making this applet look less bad with Cinnamon 1.8.2: I could not figure out how to apply styles from the currently selected theme so this is hardcoded to match pretty well with the default dark grey "Cinnamon" style.

    The dark frame around preview is not displaying (causing problems noted by Dandv): JS ERROR: !!! Exception was: TypeError: this.windowThumbnail is undefined JS ERROR: !!! message = '"this.windowThumbnail is undefined"' JS ERROR: !!! fileName = '"/usr/share/cinnamon/applets/windowPreviewWindowList@dalcde/applet.js"' JS ERROR: !!! lineNumber = '140' JS ERROR: !!! stack = '"()@/usr/share/cinnamon/applets/windowPreviewWindowList@dalcde/applet.js:140 ([object _private_St_Bin])@/usr/share/cinnamon/applets/windowPreviewWindowList@dalcde/applet.js:437 ([object _private_Meta_Workspace],[object _private_Meta_Window])@/usr/share/cinnamon/applets/windowPreviewWindowList@dalcde/applet.js:971 "'

    The title of the preview is white on transparent background. This works well for dark themes, but if the preview happens to pop up over a white background (say, a web page), it will be invisible.

    Your next version should include some sort of notification or blinking for windows that are updated in the background (Similar to the way Windows does it). When i receive messages from Pidgin, i have the Pidgin icon in the notification tray flash but it doesn't tell me which one of the several open chat windows it's referring to.

    I liked thge idea, it makes the window list more useful. But.... :) I wish it to have some enhancements: - get some of the current theme effetcs (dropshadow, some border so the thumbnail isn't get fused with the windowm beneath) - allow some configuration options, at least on the .json file... I don't know how to make an options window, that would be better, since.. - I like to setup thumbnail size (fixed or relative to the screen size, i.e.) -remove the window name (as an option) And some other things related to hte window list. Thank you for that piece of code.

    Does not group together multiple instances of the same program. I've opened two terminals on same desktop, it showed them side by side on the tasbar, and by howering any of them it showed a preview of both terminals.

    This is a wonderful applet, it makes Cinnamon so much more usable for me. The only thing I wish it would do is for the window list to shrink as more entries appear in it, so it doesn't wind up pushing other things on the panel out of the way.

    Very good, but when i choose to add the Windows List to te bottom Panel the previews don't work, only in the Panel on the Top. can you change this?

    Hi dalcde, Linux Deepin has a great Gnome Shell dock extension complete with close buttons in previews that you maybe could get ideas and code bits from: - in the unzipped downloaded folder it's the folder called "" containing their dock extension

    Hi, thanks for making this... Unfortunately for me it's unusable as it seems to conflict with "Coverflow Alt-Tab" extension :( Don't really know who's fault is it, but with both enabled text would disapear, menu gets all weird :( With the small close button (like windows 7) and without incompatibilities, it would be awesome :)

    Working perfectly dalcde! Thank you!

  20. dalcde says:

    @z06gal Fixed. It was actually my fault, since I accidentally deleted a piece of code when copying!

  21. z06gal says:

    Ok dalcde. Thanks!

  22. dalcde says:

    @z06gal Reproduced. I'll file a bug report since I just copied the code from the Cinnamon list.

    With regard to the small button to close each preview individually, was an idea very similar to the behavior of the preview of Windows 7. It was just an idea, however I am very happy with the previews. Especially when I watch TV, because I see all the live video on the small thumbnail.

  24. z06gal says:

    Yes. Right now, obviously I am on this site but the tab below reads a sports forum I was on a little while ago and it will stay like that until I double click on it to change it. I use both ff and chromium and it does it on both. When I open a browser it will read my home page but it never changes afterward unless I change it myself by double clicking on it for some reason.

  25. dalcde says:

    I don't think it's happening to me. Just to be clear, you are using a browser and switching tabs, right?

    I am having one issue with this applet. It is easier to explain if I give you an example but let's say I am on ESPN and then go to another site....after going to the new site it still says ESPN in the windows list. it will change to the current site if I click on the window list twice.

  27. dalcde says:

    @sokoc1nnamon The menu is buggy. It's supposed to work if you hover over it.

  28. dalcde says:

    4 years ago

    @sokoc1nnamon Sorry about the first point. You just have to hover to the preview, but the hover disappears if there is some other window beneath. Will find some way to solve the problem.

  29. dalcde says:

    @sokoc1nnamon Press escape while hovering allows you to close/switch to different windows. Tooltip removed.

  30. sokoc1nnamon says:

    Apple very cute and very useful. Can be improved by removing the default tooltip. And in future release also add a small close button for each preview.
