@snow If you want the idea/suggestion to get to the attention of the project developers, yes, that would be a good place. Beware there's a lot of postings there, and it's best if you prepare a good post, well explained and clearly pointing what you propose.

You could try posting a suggestion in an instance, an open post, and request comments first; then later proceed to the github if you receive favourable feedback.

Could also do that post and include some of the Hashtags that people use for development and admin work and chat -- # mastodev # mastoadmin for example. (I left a space in the hash so it wouldn't actually add this post there).
