I would like an app that provides a sensible, rational, intuitive interface for editing the apps menu.
In my case, I (at first) simply wanted to have an ebooks category that would include all the tools I use for ebooks instead of having, e.g., calibre relegated to “Other.”
Then I realized that none of the menu categories I had become acclimated to actually made any sense. “Utilities,” for instance, is an absolute dog’s breakfast of completely unrelated applications. And a TeX category would be very useful for me.
So I would like to see a menu system with many more categories than the default, with an easy option to create more submenus (e.g., Python, Mathematics, Ebooks, Statistics, Elearning).
Oddly, there does not seem to be any application in the Linux universe that does this, and those that seem to be close to what I want (alacarte, menulibre) are ridiculously short of full functionality.
So far, the best resources I’ve found are https://linux.die.net/man/1/xdg-desktop-menu and https://forum.xfce.org/viewtopic.php?id=12235, which require a lot of labor. See also this very long post: https://raywoodcockslatest.wordpress.com/2019/12/27/edit-peppermint-menu/
I’ve decided to edit the completely unorganized and illogical .desktop and .directory files in gnome to make them do what I want.
If this interests anyone else, I will share my results and/or create a Python script that will allow easy customization of the Fedora Gnome apps menu in ~/.local/share, /usr/share/applications, or whatever other locations I may discover.
