I have an iPad tab bar app and I want a popover to open when tapping one of the tabs. Is this good practice or should I avoid it?
For example, the bottom tab bar displays the following items:
my books | books | search | about | settings
When tapping 'books' a popover is displayed with book categories:
fiction non-fiction fantasy crime western
When tapping a category a screen loads a list of books within this category.
I'm asking this question because I personally think this is bad practice. I would like to discourage my client doing this.
