Been a while, but I fired up CG and it looks like you've been hard at work! Nice job! Below are a few more suggestions for consideration:
- Adding "Spin API credentials" should really be in the "Tools" menu, then selecting which spinner to use on a project could then be a project option. It doesn't feel right adding individual spinning APIs to each project.
- I see in the change log for v1.28 that you added more platforms to post to, but I can't tell which platforms are supported. It might be good to specify this somewhere (perhaps the wiki with a link to that page in the "Configure platforms" dialog of CG?).
You're doing great, and it really is amazing to see how quickly you add features. Great job man!
