I could implement a 'maintainer' system, so that the original author could come in and regain control at any time (or maybe have a request system?), but until they do, the 'maintainer' is essentially the author.
I'm thinking of reworking the add-on submission code. Nothing would happen on the user side, other than maybe some optimization, however it'll make things such as RTB Imports and Upstream Repositories much more fluid. It's all a giant set of code set across 3 (maybe 4) files rights now and is not at all modular. This may take up some of my time, but it will definitely expedite things in the future.
I should just make one of those online to-do lists.
