1. The ability to customize the hero's hit box size
Should be self explanatory, one may have a hero with a different size than normal, so they want to customize it's size.
2. True Custom Hero naming conventions
I could be wrong if this has already been changed in 1.5 dev, but I have noticed while browsing the API for the LUA system that the hero's sprite is always Tunic#, Which can be annoying if one wants to have a custom management system for the hero and different sprites for the tunic.
EX: Say one wants to have a system where you play as multiple heros, and have different variations for each hero. It is possible to do that with the current system, But they would have to keep track of what hero is what tunic ID and variation.
If anything I have specified is already possible, point it out. I want to be able to use this engine greatly and well.
Edit: OK, So I figured out that one can fully customize the hero's tunic sprites just fine. So suggestion 2 can be Eliminated.
For suggestion 1, this is an old feature request. We might do it for 1.6.
