What does your feature entail? What is it for? How will it affect existing workflows or user experience?
When more than one tab (webpage) is opened, a home button on the Toolbar would help to return straight back to the home screen tab, while leaving the opened tabs open for possible return.
The developer could add this new Home button on the Toolbar by default or make it customizable to enable or disable within Orion's Settings menu.
What are the exact ways that you see a user using your proposed feature? Please go into as much detail as possible, and provide examples of how other browsers/apps implement this feature, if applicable. If your feature suggestion adds on to an existing feature, how would it work into it to extend its usefulness?
Most browser apps on mobiles but also desktop computers have such a Home button on their Home screen (above or below), either by default or customizable by way of their various setting methods.
All if not most of their users prefer such a Home button, because it saves them from the cumbersome way of having to close or scroll back multiple opened tabs (webpages) to get back or return to the Home screen.
Examples of browser apps that have such a Home button for a long time now are: Chrome and Chromium-based such as Brave, Firefox, Edge and Opera to name just a view of many others.
