Currently on MediaWiki projects there are two checkboxes under "Beta features" in the "Editing" tab:
- Enable enhanced editing toolbar
- Enable dialogs for inserting links, tables and more
In the English Wikipedia the "Beta features" title was changed to "Usability features", which more or less makes sense, because both of these options are not beta features for a year already. (In many other languages it's still called "Beta features".) It would make even more sense to simply remove this section and put both of these options in the main list of checkboxes.
