Hello, thank you for your kind words and your support!
Unfortunately, there is currently no way to change the fact that circles have an odd number of pixels at the apex. We could work on it on a future update though. The circle plotting algorithm we're using can be found here, but perhaps we could modify it.
As for the selection tool, we plan to enhance the rectangular selection tool as well as add more selection tools in v0.9!
A platform to share palettes is a very interesting idea, but it could be challenging as we don't yet know how to do it. We'll definitely consider it more in the future.
We really appreciate your feedback!
could there be a way to export a pallet as like an array, or have it write the hexcodes of each color on the pallet to a text file and then when you reimport it, it just plugs the hex codes in? I haven't delved into your code at all, so I don't know if this method could be implemented or not.
As for circles, I ended up just making it 31x31 and that way the sprite is centred. Not sure if this will pose any problems for me or not, as I've only worked with even pixel sprites, but I'm sure it will be fine.
One more thing, though, is it possible to change the default save location? I find it tiresome to browse every time I save something, when I'm always saving in the same place.
