This is really a first for me — I’ve never turned a concept into something that was implemented, nor have I witnessed, in all the time I was subscribed to the LibreOffice and OpenOffice.org mailing list, a UI concept that originated within the design team being turned into actual code, despite there being quite a few. (On the other hand, several UI concepts initiated by developers, like “special indicators“, were fine-tuned and further developed by the design team.)
So I’m asking you for help — if you know how to get this done, please say something. If you have any comments, suggestions, or can further refinement to the Overflow menu whiteboard, your help is very much appreciated. Developers wanting to work on this and willing to initiate a rich discussion on the developer list would be great, too.
