Questionmarks... well... to be honest, i would much rather see a standard android settings interface for everything. You might consider it boring now, but in fact it's simple, easy to grasp, beautiful, battery-saving. It doesnt need complicated things like extra help texts hidden behind question marks because there is plenty explaining text already, way more than with your one-word-labels. Almost all other apps do it that way, it will look pretty in ics and below, etcpp. It's just standard and people expect it.
Custom ms-windows desktop emulation things on the other hand (subwindows, close gadgets, ok/cancel buttons) are not androidish and confusing. And the more work you put into your own ui (like the question mark thingies?!), the harder it will be to "get back on the proper path" later. Of course you are in love with your own button inventions right now... but maybe that will change with time.
I think Locus can have a really fancy main screen (the map view) with loads of custom things all around, but should stick to android standards everywhere else.
Android standard. Simple, Easy to use, Beautiful.
Just my opinion obviously, yours may differ
