make the top of your blockhead whatever color you want.
In the Avatar menu there's a button "Color Set" which lets you add new colours to the preset list for setting any part to any colour.
what if you could put two hands on the weapons like shotguns, bows, ect.
Bushido suggested a shotgun or rifle-style 'two handed' stance which would go well with the left arm/right arm/both animations that currently exist, so that would be a good idea. That does need Badspot to make it part of the player model, can't be done as an Add-On. (I tried adding animations in the past but they didn't register at all)
what if you could put in a folder called "add-on maker" in the blockland folder.
Right Click -> New Folder
could you make a backpack to put stuff in and can you put in more item room
Possible as Add-Ons. Someone already made a player type with extra item slots. Five is enough for most deathmatches anyway.
put the fist weapon as an item that comes with the game?
There are two. The "Fist" weapon on some servers is just a generic sword edit that sounds bad and is really lazily made (swing arm up and down rather than an actual forward punch) The "Fists" one uses material from Team Fortress 2 and it probably wouldn't be legal to go distribute that as part of Blockland, especially because Badspot is selling it.
make it so we can see the chest part again?
Fix your graphics card.
make a running mode
You are basically in 'running' mode all the time. You can press C to walk slower.
