I’d like to see an option to open a particular post as a different user. Mastodon clients have this and I find it pretty handy.
ie. Clicking the menu on a post should have “open as” which then lets you select one of your other logged in identities, and switches back to the post from that account.
The URLs Don’t match, not even the post id’s are the same. This would be a big point of failure. Especially when its on different instances. The steps you made have the key issue in step 3, thats not possible.
It is possible.
Search for the “Lemmy link” URL. Works on the web interface, no reason why it won’t work through the API too: (it’s the same theory as doing community lookups)
