Not sure if this is the right place to put this, but the bulk editing feature may cause some problems because:
- You can edit the result of a calculation question
- You can edit the photo upload question and change the photo filename without uploading it.
- You can change an answer which may have an impact on the skip logic of the form and require other changes had it been done in the usual way.
I feel that a careless or tired validator may very well make the above mistakes which can cause serious problems in the integrity of the collected data.
