Years ago, when I still used only Windows, I used a program called WindowBlinds or DesktopX(Can't remember which one did what I liked).
The 'program' allowed me to add functionality to my open programs/windows. Instead of having just the options to minimize, maximize, close, & window menu... I was able to place buttons in the title bar of the window/program that allowed me to roll-up, toggle opaque, TILE ALL WINDOWS (where in the world is this in Mint?).
These functions are pretty basic, especially at this stage of development. I'm not a coder beyond cnc, or I'd do it myself.
I would think there would be some options in the Linux world, and hopefully this new topic will lead to a discovery/lesson.
If you know of any programs, techniques, or a step-by-step, please let me know.
