workspacer VS win3wm

The topbar is part of workspacer just heavily customized you can get it here: https://workspacer.org

I will definitely give this a try. Have you used Workspacer?

I usually only watch one stream at a time but the few times I have had two open I just kept a single chat open. Pressing the + next to options when you have a tab open lets you open another side by side, no idea if there's any way to drag and drop a tab there though. More generally for window management I use https://workspacer.org on windows and have filters to automatically open chatterino and mpv on the same workspace with a 20-80 split.

FancyZones in power toys and https://workspacer.org/ (not tried it personally)

For Windows, the situation is even worse. While I was forced to use Windows at work, I used workspacer for a while. That was better than no tiling but still a huge pain to use (flickering on every key press in some programs, called "epilepsy mode" by my colleagues; slow startup; restart or crash every time the display configuration was changed; almost no documentation or ability to customize it). All other tiling window managers for Windows were even worse, some not starting at all, being incompatible with Windows 10, or not supporting multiple displays.

Have you looked into methods of hotkeying or auto-removing windows titlebars once a window belongs to a container (maybe they can auto-restore if a window is floated/unmanaged)? I know that workspacer and win3m have something like this.

Here's another one.
