3 monitors: 2K laptop on a stand, 4K rotated, 2K rotated & sometimes scaled to 4K. Lots of screen space.

Windows in strategic positions, sized small to fit the content. I removed maximize. I never maximize. I full screen a single game or video to one of the monitors when desirable. I rarely minimize. A dock on the bottom of the laptop with windows grouped by program -- very manageable. Placement and size of windows. Being able to see everything at a glance. I wish XFCE could save window positions and sizes.

No tabs. My default is new window. When desirable, I only create new tabs in a web browser window. Programs get separate windows, no tabs. I have custom CSS to hide the tab bar when there is only one tab. No tab bar is my default. I manually save URLs if important and close web browser tabs if I've gone down a rabbit hole. Destroy all tabs. My browser clears all history. Starting the browser opens a single custom web page window, no tabs, with recent URLs that I saved.

No tabs.
