Table has column property.
Everytime this is changed all columns in that table are resized without question. Also they are rezied wrong if you have not default “distance between columns”. This is really irritating.
Can you ask Yes/No question and/or add a setting/icon (on toolbar and ribbon, both not just one) which will change this behaviour?
Promoted to planned status. We’ll probably add a confirmation message box to LL22.
Probably and in one year? 
We usually don’t add unplanned ressources during the lifetime of a version. We’d need to have the text translated in all the umpteen languages we support. As this is a very visible change, English will not do. If we should run an additional localization cycle during the lifetime of LL21, I’ll make sure to get this into the product earlier.
