I’ve seen users get lost a number of times when drilling into details and reaching a level where no further click to detail is available.
Say, for example, you have a list of projects. Clicking on a project name takes you to a screen with all . users assigned to that list. Clicking on a user takes you to a screen with all projects to which that user is assigned. Those listings are not clickable for detail.
The option is to back swipe … but the swipe carets being missing is not obvious to many users.
Likewise, a “Home” tab at the bottom of a screen gets missed if the data list on the page is short since their eye is not directed downward.
A “Home” button just below the list is obvious, catches the user’s eye, and draws a click.
But I don’t see a way to use that button to take them to a Home tab vs. a screen based on one of the sheets in the app.
I think this kind of internal link to tab would be useful in many situations.
