Implement "Web Apps aggregator" mode to provide a separate window with multipe web apps and quick switching

[MurzNN]

Floorp introduced the Progressive Web Apps feature, which is great! But, having each web app as a separate window is not very convenient. Therefore, there are different web app aggregators that exist, for example, Ferdium - it is a very convenient app! Also, there are Rambox, ElectronIM, Hamsket, Franz, Tangram, Shift, Biscuit, Wavebox, Singlebox, Stack Browser, etc.

But the issue is that all those apps are built on Chromium and Electron, which is not good for Floorp fans :)

But Floop, actually, already have almost everything that those apps implemented: a sidebar, per-tab isolated profiles, etc.

So, the idea is to implement the same feature using Floorp - a separate window with a large icon-based persistent tab switcher, and UI to manage these tabs. Or, maybe even release this as a separate app, based on Floorp? What do you think about this idea?
