Experimental feature sidebar - reporting site?

I tested this feature for a while on and consider it as very good one utilizing excellently the side ratio of current PC screens. However I also have some enhancement ideas.

(MS’s ribbon are reducing the modern PC screens usable area whereas the sidebar increases it. )

Is there a site where feedback on experimental features is collected?

The sidebar is no longer experimental in branch 4.2

Maybe post on the Design mailing list…

There are already quite a few threads on the Sidebar e.g.


@Pedro1 - Thanks for the links Very interesting report from mirek2
I am now curious how it works in 4.2
