Hidden Toolbar Issue

I feel that the hidden toolbar isn’t “hidden” well enough. If I tap anywhere on the screen to scroll (unless I tap on the very outer edges) or to highlight something, the toolbar at the top reappears. It’s very annoying when scrolling because it cats uff the top line.

Could we fix it so that it only reappears when we double tap at the top of the screen where the toolbar is supposed to be?

Also, can we add a left handed mode or do like the Kindle device does where there are “zones” you can tap to go the next page.
