When moved the message-filters should be updated. Reproducible: Always Steps to Reproduce: 1. create a subfolder in account 1 2. create an message-filter for that subfolder 3. drag & drop the folder to an other account Actual Results: folder is copied Expected Results: TB should ask if the folder should be copied or moved. When moved TB should ask if the message-filter should be updated.

This looks both easier and safer than not providing cross-account moves of folders at all and thus forcing users to delete the source folder after copying to the other account. Might be a good compromise to offer cross-account moves while preserving the ux-error-prevention of not allowing cross-account moving by default. Advantages of this proposal: - allow cross-account moving, but only with explicit user consent (ux-error-prevention) - prevent unwanted data duplication from current default, cross-account copy. - remove hassle from inted cross-account move (currently requires copy and delete source)
