Is it possible to change the presets palletes? Is it also possible to add more to the presets menu?
I like the current palletes but being able to change what the defaults are would be useful and save them permanently as the new default aswell. Being able to manually ad new ones would also be great
Unfortunately no. as an alternative to being able to change the default palette, you can save a .pyxel file with a different palette setup, and the use that as the base file for your spriting.
My own workaround for not being able to add more presets: make a folder named "palettes" that is easy to access in path, then use Color->Import from image
Fair enough, mabey it'll be made into a feature someday
