You're welcome, glad you like it :)

I made this one as simple as possible and basically this popped out of my mind as-is <why not> because I'm lazy to pop up a terminal and write "code ." :D VSCodium does not have that much of extensions, so to be honest I never had (and still not having) plans of implementing it, nor the flatpak variant - It might be just me, but why wasting couple of more gigs for the same program but in flatpak version, if there's the native version which takes less space, works as a dream OOTB and doesn't have those usual permission problems that flatpak has. Basically implementing these additional two variants would overcomplicate the simplicity of this action menu, and by this I would go against my own goals... :) This is why I also made the dependency paragraph, making it clear to install code from MS's repo, so it's gonna work as intended. But as always, its open source so feel free to tweak it to your likings :)

for vscode insiders: sudo ln -s $(which code-insiders) /usr/local/bin/code
