Hey there, I recommend improving usability in following ways :-)
- Hide all settings with just one option (server selection #4389 (closed), php-version, spam filter, ...)
- Split SSL into an own tab #4546 (closed)
- More global settings and limits #4857 (closed)
Would be awesome to see some of there improvements in one of the next versions. I can help with some of them for frontend. Just let me know.
