With this. Just remember to make a Brushes folder where your powder.pref is (or powder.exe if you don't know where your powder.pref is); last time I used this it didn't do it by itself. Never mind, it does do it by itself now.
Ctrl + shift + right clicking on any element of GoL deletes all connected GoL elements, even if they aren't of the same type. Not really a big issue though
Suggestion: can_move[moving type][type at destination] = 4 means particle is eaten

Because can_move value of 1 no longer to means eaten.
I think if has Lua element, can_move = 4 to making simulation faster.
