Thanks for all the feedback:
@Spyral: these should be fixed in the next build. We've experimented with a layout with fewer boxes and didn't like it but once we get through all the more immediately addressable feedback we can experiment with some other options.
@lookslikerain: yeah, I'm feeling like I'm probably going to have to bow to the inevitable and add a screen of 'expert' options for flash to cover stuff like button order and answer colors that would not be conveniently addressable through a custom test type.
@fiftyfour: we're fixing the top bar overflow in the next update, actually going back to 3 fields too. We're experimenting with moving the drawing box toggle to the bottom right of the definition but if people hate that we'll find somewhere else to put it, it's tricky because only a small % of users actually seem to use that feature but for them it's incredibly important that it be obvious (when upgrading) and easy to reach.
@Spyral again: that bubble size issue is on Apple's side, sadly.
@jurgen85: we experimented with a bunch of looks for that bubble and found we really needed a bit of a background fade to make it visually distinct while still feeling like a Liquid Glass element, we can play around with the levels of darkening though.
@Shun: sadly the new Liquid Glass toolbars don't allow us to customize the spacing between sections so about the only way we could do this would be to have every button be by itself, but I suppose in iPad there's enough room that it might be justifiable and the current split looks a little weird.
@fiftyfour: thanks, these should both be fixed in the next update.
