As a current jool user, I'm very interested in this project.

Hit me up off-list and we'll work out a workflow and all that. paultag -- ⢀⣴⠾⠻⢶⣦⠀ Paul Tagliamonte <paultag> ⣾⠁⢠⠒⠀⣿⡁ https://people.debian.org/~paultag | https://pault.ag/ ⢿⡄⠘⠷⠚⠋ Debian, the universal operating system. ⠈⠳⣄⠀⠀ 4096R / FEF2 EB20 16E6 A856 B98C E820 2DCD 6B5D E858 ADF3
