Feature Request: Built in web browser

It would be nice if when clicking a URL (especially on mobile) if the site would open within a built in browser OR allow the selection of a specific browser within settings to force that specific browser to be used. Especially on iOS the default browser is always Safari and it would be nice to be able to select something else.

A built in browser might also solve another problem I'm having when posting links to sites that require authentication. Perhaps a built in browser could still generate a preview of the page rather than just show the preview as 'login'. Discord implements a small browser within the app that works quite nicely for this type of quick browsing. I could also see making this a user selectable behavior.

Start by locating the mobile URL-opening behavior and the settings that control link handling, then review how authenticated links generate previews. Define whether the feature should embed a browser, select an installed browser, or both, and verify the chosen behavior on iOS before considering the request done.
