Don't worry about it! Too many people aren't critical enough, I think. I really appreciate the honest feedback (even if I get defensive about it!). A lot of the stuff I whip together in 3D doesn't take much time at all, and I like it more than the grey backgrounds! It's getting there though x3
I'd love to do more with the UI too. I've changed the fonts so many times now, it's driving me mad. I had to decide on one that is shared between MAC and PC users for the time being, since I was having a lot of people with MACs who didn't have the font I used on PC.
If THAT surprised you, you should have seen my BFs reaction to the car door noise I has used when I first started up. There was no music, and just that lone sound that randomly spiked in.
