Customizable Mobile "Add" button

Use case or problem

I’d like to be able to Hide the “add button” on the bottom of mobile editor, or, could I directly Open a new tab with it ? (Long-pressing is also great)
That would be more convenient.

Proposed solution

Providing a setting to define the behavior of the “Add” button:

For example, directly assigning it to a specific command (such as opening a new tab) instead of displaying the “Quick Switch” suggestion.
It would also be beneficial to have separate settings for the “click” action and the “long-press” action.
