Hey there! Just came across your Texel Paint app and am interested in seeing how this goes. Looks like a really handy tool for easily coloring low poly models. For indies who just want straightforward painting, this is a godsend.
Since you stated to name any recommendations we may have as you develop this app further I figured having a pixel/dithering brush might spruce things a bit, especially for those who may want a 2d pixel kind of aesthetic on their models. Usually doing this involves going to something like Photoshop or AeSprite and being relatively unaware as to where you're painting until its too late.
Other than that, maybe a layer mode or a "decal" mode. This is in case you wanted an extra or separate texture layer on your model for things like rust, blood, dirt, stamps, scratches, etc. on top of the original color layer. This can be good for easily testing multiple texture or wear and tear on models for games. (Like if you lose health, you can have a game switch textures to a "beaten up" texture without having to mess with your original model).
I hope that this is helpful in some way, and look forward to seeing where Texel Paint goes from here. I don't know if these recommendations would fit or are unrealistic, but just putting them out there in case. With that said, thank you for the work you're putting in already and hope to see this come to full release.

Hello there, I was trying to use Palette Studio and love the simplicity of getting all 8 angles at once. This is such a time saver for those on the Doom Modding scene and for indie game makers. I applaud you for your hard work.
, unfortunately I faced an issue. This is the error I was given.
