After a while of working on it, it's finally ready to be used (although there are still some improvements needed here and there)

Overview of changes:

• you can now use multiple sprites to build your pngtuber, this makes it so you can do far more advanced models
  
• models can be migrated from PNGTuber Plus
  
• new layers like for example the "TextRenderer" which turns your png into text
  
  
• stream deck plugin that's live in their store: https://marketplace.elgato.com/product/pngifyme-e7d02258-4bc9-46a2-a073-c6ed6c749c91
  
• performance optimizations for regular mode
  
• new safe files which now include the images in the save file
  
• auto image optimization: cut off unneeded whitespace to allow for quicker rendering
  
• websocket server that allows apps like stream deck to control PNGify.me
  
• lots more
  

As this update has been a major overhaul of the entire program, it will mess with your save data, you'll likely have to set some stuff up from anew.
