I don't like the usage of large, puffy buttons with very pronounced gradient in BIAB. I would prefer a more flat /neutral look (everywhere) If it was up to me, I would get rid of at least 1/2 of the button graphics and replace them with just text buttons.
If re-design will be done with future in mind - fully configurable, you can have different "themes", and if someone is into puffy-gradient stuff, they can have this look in a matter of of a few clicks.
