- The ability to change our own names
- 2 Factor Authentication of any kind
* Preview post before actually posting it - Deleting a post after it's made
- Search multiple tags at one time
- Requesting our data be sent to us (which is actually a legal requirement in the EU)
- Blocking other users
(Another legal requirement) - Any kind of account connectivity to something like Discord or Twitter
- Language options
I'm sure there are more and maybe a few of the features I listed exist under a different name or in a hard to find location but it just feels like some of these should be easy to implement and would be good quality of life changes for devs and users alike.
Edit:
- Preview a post - Is a feature (Not sure if it wasn't until now but I only just noticed it)
- Blocking other users is only required for apps on the App and Play stores
