> While waiting for reviews, I took the liberty to add the third of the possible future follow ups to this PR, aligning the error handling in the rename and move (to) folder dialogs.
These now use the `TextBoxErrorStyle`, which means that they look the same but have error tool tips.
In addition, there is now a warning when move folder will merge folders, for the dialog and the drag and drop. The user can still proceed by confirming the dialog.
