I have just installed Ubuntu MATE 22.04. I like it quite a bit and I am considering switching all my computers (laptop, desktop, work, and home) to this distribution.
The one issue that holds me back is the dearth of themes that distinguish between active versus inactive (focused/unfocused) windows by changing the colors of their titlebars. I see that the "Windows ME" theme does that, but who would want a Windows theme on Ubuntu?
Perhaps there is a way to customize the titlebar colors on active versus inactive windows. If so, then I would greatly be indebted to anyone who will show me how to do that.
