Combo improvements I would like to see

this is just a list of combo improvement I would like to see implemented or edited

I would like to see the devs implement 4 different collision boxes for combos
- solid (already implemented)
- liquid
- pit
- warp

assigning something like a fully liquid and pit combo would not be recommended but in this case would be possible

To be truthful I don't actually know the difference between types and flags however I would like to see the following possibilities implemented

- diagonal conveyors for both water and ground
- GB style liftable combos
- GB style diggable ground
- GB style moving combos
- GB style chests (multiple) <- would require some way to assign items to the chests

I would also like to see a item requirement box where you can check the item link has to have to use the combo as well as the level the item has to be

I would like to help with this effort.
