Some things I learned about the Mastodon web UI:
The profile page of a user on another server won't show all of their follows/posts. Open it in a new tab (by middle-clicking their username in a toot) to view them all.
To boost or fav a toot on an external site, copy its URL into the search box on your local instance. The toot will be shown as a search result.
@dredmorbius Cool! But I can't view that toot from my instance. :(
@blinry It would be really awesome if it could display followers on my current instance and in paranthesis maybe the global count. If that's technically possible...
@blinry Oh interesting, I did not know you could do that with urls in the search box.
@blinry that sounds really unpractical, at least the last one
@saturno Yeah! :'-(
