Bulk remove specific values (from multiple input field?).
Issues
Entity is not validated prior to being saved
Invalid values can be submitted.
Add a "Prepend to the current value" to the "Modify field values" action
Add an option to prepend values. Currently only append is supported.
Allow user selectable form mode for bulk edits
Currently hardcoded to use bulk_edit display mode.
Current dev version broken - saves all fields even if only one changed
Only changed entities should get saved.
Save button on each row
Add a save button to each row.
Modules

The UI for editing takes a few clicks, would be great if it could be simplified.
