I've found that the lack of good footnote handling in Gemini is a real pain in the rear.
Consider footnotes in a book, you see the superscript 1 or the star or the cross and you know you glance towards the bottom of the page for that content, then jump back to where you were. On books, in dense text, you can put your finger on your current location, look to the bottom of the page, read that content, then pick up where you left off.
On a screen it's harder, since going to "the bottom" involves n pages of text to be scrolled by. If I hit [End], I don't know how many [Pgup] to hit to go back.
I can hit [Pgdn] a few times and count mentally (which sucks, and takes me out of the flow), but due to the way text is flowed, reversing with an equal number of [Pgup]s will usually wind up taking me somewhere above or below where I started.
This disorientation is not desirable.
Inline footnotes on most rich text sites usually have a link directly to the footnote, and then a back link which jumps to where the note was referenced. This is the best of both worlds. I'm on board with most of the Gemini limitations, but I see this being a no-brainer addition to the protocol if not a sane client.
