Hey, first of all, awesome tool. I love the styling of the sprites, is the general purpose design I've been looking for a while! I just wanted to inquire about the roadmap item related to adding our own art to the tool? I loved the tool that I've already implemented into my project, and did my own adds to it, but I had to added on Photoshop after exporting, and would be awesome to match the animation and what not, to add the accessory to an specific category and have it available for future character on the fly!
Also, and this is waaay less critical for a pipeline than the previous point, but having accessories and other parts with an offset (just a few pixels up, down) would make wonders to create more unique characters. I notice that when, wanting to have a character with glasses but without obscuring the eyes, I exported the glasses separately and just added them in PS, just moving them a couple pixels up, and voila.
In any case, wonderful tool! Definitely worth the price.
