The tab view... (Thank you Videotrack!) I believe you were the one to show it to me smile I strongly disagree with the interface with those huge colorful buttons. I mentioned this in another post which fully mirrors what you said. Modular is the way to go Biab or Plugin. Display and use what you need, hide the rest. Tabbed view solved that well in BIAB, why not use same or similar idea in plugin? For example "custom" tab can be used to add custom views or functions/shortcuts.

Rob,
If the "stabilizing" will leave ample room for future development sure! But I was under the impression from other discussions that the further you are into programming, the harder it is to go back to make room or adjust to implement core features.(I do consider volumes as a core feature)
