Thank you! This button used to be there, we removed it because Home button should bring you to the last page you were on. So if you were on the tab switcher page and opened a tab and clicked home - you get back to tabs. So your scenario with an extra click should only happen once (for a series of tab switches).

I find myself getting annoyed by this issue once in a while too, so will keep an eye on it. Maybe we'll bring the button back if nothing better comes to mind.
