I've noticed a few things while browsing alpha.glitch.com that could be improved. Often this is just something minor - not worth a topic of its own.
HOME
When the game is open, your friends online are listed on the HOME page. And even though it looks nice to have all these avatars lined up, it bothers me that I have to scroll all the way down to get to the auction part.
Also, if someone is unaware auctions even exist it is unlikely they'll find them.
Possible solutions:
Display only e.g. 5 friends online and have a *view all* link.
Move the auction box to a more prominent spot.
Depending on how important auctions will be in the final game include a link in the game interface.
BADGES
The way achievements are displayed at the moment confuses me. I am guessing they are organized by date.
I would prefer for the badges to be displayed in groups, e.g. badges you've earned using an awesome pot. Different icons/graphics would be nice, too.
A Tree of Achievements (similar to the skill tree) would be very helpful.
The info boxes which appear when you move your mouse around are a little buggy at the moment. They don't close properly and you often end up with a screen full of yellowish boxes only a refresh can save you from.
