2.6.12 Don't hide the tab bar with buttons
Related to the audit.
Description:
The breadcrumb appears to be an important part of the application navigation. Yet, it can be hidden, for example when a user clicks on the “Library” button, which is included in the tab bar.
Recommendation:
Hiding or replacing the tab bar should be avoided at all costs. Instead, modal windows or side panels can be used to display categorised or hierarchical information.
