a platform that enables designers to relatively easily contribute to open source projects without learning git
Reading this made me a bit sad.
On the one hand, I understand how tools like this could be a hurdle for someone who isn't heavily invested in their use. And on the other, as someone who has tinkered with open source projects, I know that as hurdles go, git is the first of very many hurdles that must be cleared when contributing to a large, mature GUI program like this, and it's a pretty low one at that.
It would be great if more people could contribute to and help develop open-source versions of tools they themselves use, but I can certainly see how tough it can be starting out
I know very little about GIMP or other OS design software, but does this software have a plugin system that designers could use to extend the software so they can use it how they want?
That would be another thing to look into
