Hi, i was wondering if it would be possible to add more costumes/expression toggles to the software? preferably just a "+" to add an additional one. pair this with a stream deck and it would be possible to have more outfits and expressions! :D 

if there are no plans to add this, is it theoretically possible to modify the source code yourself to get that option? and if yes, how easy is it to do it? i'm a newbie programmer :c but i know the source code is available on Github :D

Having glanced through the code base, the costume count is currently hardcoded. I think upping it would definitely be possible though. Godot's pretty straightforward to pick up, honestly; there's a lot of good documentation online and not much required to run software.

What I kinda want to play with too at some point is adding a default visibility to sprites. As then you would be able to say switch out a hat with a head of hair without needing to use a costume slot.
