This was a big pain point for a lot of us and we're so excited to roll out an update to our UserBit editors. Now you can:
Edit highlighted text
Delete highlighted text
The tag count will automatically be synced
Undo (Ctrl + Z) Redo (Ctrl + Shift + Z) on the editor
These updates will work both on responses as well as notes. These were notoriously difficult updates to deliver but we're so happy about the improvement in usability this will bring for our researchers!
