Here's another Mastodon iOS Shortcut. This one lets you view someone's Following list (even if they’re on a different instance) and open one or more of those Profiles in browser tabs to see their posts, so you can figure out who to follow with less friction (and then use my other Shortcut to follow them without the copy/paste steps).

Once added to your Shortcuts app, just share a Profile to the Shortcut to use it.
