On mobile I use(d) Relay for Reddit browsing. The app has a feature that I miss in Jerboa.
In posts/comments, [hyperlinked text can be long-pressed to reveal the destination](hi there i am a URI to any other website) in a pop-up overlayed on the link (sorry, I don’t know the proper term for this UI tool) without actually opening to the link. Upon tapping off the pop-up, it closes and I tap on the URI to follow through to it, or not, as I wish. In Jerboa, pressing a hyperlink only opens it, site unseen (pun intended).
This change would be useful because sometimes I don't want to open the linked page, given the target (e.g. youtube, instagram).
In Jerboa I see no way of discovering the URI of a hyperlink without following to it, which would be convenient to avoid.
