The list is always tentative and subject to new info for prioritizing. If you’re on here, reading this, and participating I’d prefer to prioritize what you all want.
A 'Dark Mode' theme please.
The 'sub topic' should (IMHO) also be implemented, so that the content can start and take on some organisation: there are many very good posts that have simply become buried, which may not have been the case, had they had a 'sub'.
As an add-on to this, maybe a way for users to 'follow' a thread?
