Tabs are used a lot in the user interface, especially to show related entries when viewing an entity. After the switch to the Bootstrap framework they have to be rewritten to remove a lot of code repetition and logic outside the templates again. Most of this will be refactoring work in the backend that won't show but we try to improve the tabs when we are at it:

• If a tab has no related entities to show there will be no number right of it (instead showing the number zero)
• Buttons are only shown if the user has sufficient permission
• If a tab has neither buttons or data to show it won't be shown at all
