Main idea: use multiple windows and each for a particular project. Can leave one as a catch-all.
From top right menu > More Tools
> Name Window...
, name each window. Use certain symbols or formats to differ manually renamed windows from page original tabs.
The name isn't directly visible but will be shown in different scenarios:
- on Mac, using Mission Control or App Exposé
- on Windows, on taskbar or switch windows using Alt-Tab
When open new tabs, consider moving them to the corresponding window. Either by dragging or right click on the tab and choose Move Tab to Another Window.
