We discussed this within the "Welcome" forum post but I wanted to put it here in suggestions so it doesn't get forgotten.
My MSFS Livery Toolkit is primarily hosted on Github here. I do keep a copy on flightsim.to for discoverability and it's already a pain to upload in two places then copy version numbers and release notes.
I'd love to post the addon here too, but having a 3rd place to add those details is too much. So if you could add some ability to sync from Github (either fully automated or a one-click sync) that would be fantastic. Obviously this is only applicable for add-ons posted on your site which link to a Github repo, rather than hosted directly.
