Howdy, I just found this map editor and I'm definitely loving it already. I read on another thread that you aren't ready to make this project open source yet, but I'm curious if you'd be interested in some help with developing new features at this point. I'd love to contribute to the project, but I understand if you want to wait before adding others onto it.
A feature I'd really like to see is the ability to put in a hex code for colors in addition to the color picker. I like to create my color pallets with hex codes, and having to find the shade I've created through the color picker is a bit tedious.
