I fixed a couple bugs and added a key binding thing to make it easier to use
First bug was where you entered the spray mode, but could drop or unequip the spraycan and continue spraying.
Second was with loading sprays, if a tag existed in an initially unloaded square then the load would fail, the tag would show but they wouldn't be the correct color (all white.)
Diff for these 2
I also added key bindings to more easily spray (keys.lua.) There's no color selection it just grabs the first non-empty can from your inventory. You can change bindings in the main options screen. To delete a bind you'll have to edit Zomboid/lua/keys.ini in your user dir and change the number part on the right of whatever option to 0.
Default binds are T for the 'Looted' checkmark, Y for the not safe exclamation mark, and the numpad for the 8 directional arrows.
