The expand/collapse feature was dropped in version 7.0, unfortunately. However, this has been a frequently suggested feature, and I would also like to see it return in 7.4.
For example, the user-defined forum sorting options was dropped in 7.0, but added back in 7.1. Just wait for the changelog to see if it is added back. I know blogs are planned for 7.4, and I have also heard rumors in changes in the UI.
FYI, version 6.5.5 is still available for download, and it has the expand/collapse feature.
In addition to the expand/collapse feature, some of the top features I would also like to see are:
- Public polls
- Nested and Hybrid views for posts
- WYSWIG editor
- Thread subtitles like in Invision Power Board
- Multi-post quoting
- Search function for user list like in UBB.classic and many competing forum software.
