Maybe I didn’t well understand the purpose of the Before/After view or there is a possible bug.
If I make a change, this takes place first on the “After” window and after a few moments also on the “Before” window. There is just a moment to see the difference.
I mean:
“before/after” view enabled
lock the “before” view
do all/some changes until it’s OK
then unlock the “before” view, that is refreshed and everything is ready to be locked again for any further improvement to be compared.
I would understand this a little more. Of course, having something like a button to manually refresh would me more elegant and comfortable than having to unlock and do and undo something in the editor to refresh the before view.
