I wasnt even here last month but its great to see that we have a lot of different ideas. I'm just refreshing it then if thats ok
Here's what was in Panda's post:
1. Make the Avatar picture on the bottom bar be selectable so you can heal the picture to heal yourself.
2. Create a MMO party like display that lets you see your teamates HP and Mana. Also make it selectable so you can heal or buff them from it. Create a toggle for it so you can make it disappear if ya want.
3. You should be able to view your pets from a similar display. Dont neccessarly need to put HP bars on it, but at least a number so you can see how many you have.
4. You should be able to select the Item and Ancient item shop from a distance so you can review items and item costs from anywhere on the map.
5. Unlock the keys bound for Camera use in the options. Some of us want to use Q and E for other things aside from rotate camera.
6. Show the name of the game in the lobby your in while your waiting for a game to start. Its frustrating to join a game and then try and invite a friend to join but cant remember the name.

Although I'll be honest, they seem bigger than my little things - they actually add to gameplay rather than being more aesthetical like my ones; for example I think self selection is bigger than a little thing - I've often wishes for such a button, it's a great idea! 
Another trivial one I'll add to my list is the Demigod rectangle selection boxes aren't very good - Rook and Oak's come to mind; it's not immediate through much other than experience which demigod it is, as it's often a blurred closeup of a portion of their face.
