I see the word Standard a lot in describing your themes. It can be confusing. I have some suggestions:

-c light, medium, dark
-t glass, doder(dodger?), beryl, ruby
-s fullsize, laptop
-o standard, color

It's not hard to make a GUI to do this, if we can with plugins. Not sure why themix-project/oomox#146 was closed...
For example, I'd like to see Qogir, but I don't know how to make a plugin. The same goes with the OSX Gtk themes.

The Cinnamon main menu is so big that it takes up nearly the entire height of my laptop screen. How can I make it smaller, say half the screen height?

Expected behavior: Usually, if you drag your mouse to the very top of the maximized Firefox window, the tabs and new tab button are clickable.

Bug behavior:
When using the Windows-10-Dark-3.0-dark window borders, you cannot select tabs or click the new tab button when your mouse is all the way at the top of the screen. Instead, you grab and drag the Firefox window itself.

It would be nice if You pack and add your themes to Flathub,
Than we can properly theming Flatpak apps.
