Thank you for your kind words. It means a lot.

Grouping windows would be an OS-level task, and the solution is the multi-desktop/workspace feature on most modern OSes, or you can try third-party app alternatives (which I'd do for Windows10, as I currently find its built-in feature a bit lacking).

But yes, naming can in a way facilitate grouping. Good thinking! I do it too, and I intend to document it as a tip in the help page for the next update. I like to go with e.g. news, news/tech, news/politics, etc. With whatever naming pattern used, typing "news" in the panel will show a list of all the news windows.
