Well, this is my first somewhat real project and I like to believe I have learned a lot since I started, so if you can give any feedback about it preferably but not mandatorily in a constructive manner, I would really appreciate it.
Scan the rest of this FAQ and see if said issue is mentioned. If this is not the case then look for the log files on /home/USER/.config/automathemely (some may be hidden), and if they were to be empty try doing a single run by doing automathemely and checking its output. Then open an issue with the contents of said log files or output and a brief explanation of the issue.
That's great! Open an issue and explain how you plan to achieve it, or better yet make a pull request. I'm all ears!
I have a suggestion for a desktop environment or application but I am really not sure how to implement it
That's okay too, you can still open an issue with your suggestion and I'll look into it. But no promises though.
Make sure you have GNOME Tweaks (also known as gnome-tweak-tool) installed and the User Themes extension installed (either from the gnome-shell-extensions package or from the Shell Extensions site) and enabled.
Yes, this is the case with GTK3 applications which for some reason have no obvious way for them to tell them that the theme has changed unlike GTK2 apps. This is an issue even with KDE's System Settings native kde-gtk-config and as far as I know has no current solution other than closing them and opening them up again.
Wait, don't Atom and VSCode already have their own extension to automatically switch their respective themes?
Well yeah, they do. But since each have their own definitions of when to switch said themes I found it annoying to have a mismatch of desktop themes and their themes. You can keep using them if you want to, but I thought it would be nice to give you an option.
As my shameful commit log may tell you I did already try setting up Snap only to fail miserably because I think I am too st00pid to make it work so I settled for fpm, but if you really have any other recommendation on how to make any other thing work, please PLEASE let me know...
Since the inner workings of KDE are still very much a mystery to me even after trying to mess around with it for some time, I've settled on simply switching the complete Look and Feel theme as is through lookandfeeltool.
In the meantime, if you want to tweak something on it (such as the icon theme, wallpaper, etc.) you can make your own Look and Feel package by copying and pasting the directory and editing its files to your liking and changing its name to something else in the metadata files to something like Breeze > Breezer.
