Combine taskbar quick launch and currently running apps

[Melodeiro]

Describe the solution you'd like
Talking about behaviour from Windows 7+. And there is another behaviour which i would like if you can implement - showing that there is a multiple windows opened:

Describe alternatives you've considered
A quick workaround would be to use some kind of a matching filter. For example, match by proccess name (with the ability for user to manually write its name). I have seen the similar behaviour in Linux OS, not sure which one but i think it was DockbarX taskbar.

Additional context
Probably it was described in that message: #52 (comment), but was skipped at that time.
