There's no built in functionality for this at the moment, though it is something I'd like to add. You can technically do it by hand if you go to the save data folder (pressing ctrl+alt+shift+o in the program should open it in the file explorer). Each project is a separate directory in there, so you could upload and share those somewhere, and anyone could manually add them to their own save folder. But obviously that's quite a hassle!
Glad I found this! - thanks for putting in that hotkey for opening the project directory. I ended up copy and pasting all the colour values across different types of my chips for consistency's sake (Logic chips are Red, State chips are Yellow, etc)
