Here are some features that have been requested to come back to M6:

• Show All option to be configurable on tabbed layout dialogues

This would simplify some maintenance task on the dialogs contents while allowing the users to maintain the tabbed structure to keep everything organized.

• Tabs dropdown to switch between tabs when the amount is too high On scenarios like this, in M6, the user would have to navigate by using the navigation arrows instead of having a dropdown to move to whatever tab he has to work on.
