I have three gemini clients on my phone, Ariane, Deedum and Xenia and two laptops, one which has both Amfora and Lagrange and the other one only has Lagrange on it, I wasn't able to download Amfora on it.
Anyway, all of them have copious amounts of bookmarks, I love slow surfing gemini on my phone in the middle of the night when I can't sleep, but I can't sync them so if I remember a page and have forgotten the gemini URL on my computer but remember it's on my phone on one of the clients, I go there and find it and carefully type the URL on my lets say, my computer gemini client and then I will bookmark it there........it's tedious I know but it is what we can do for now lacking the sync capability. It's a minor inconvenience but one I am willing to put up with as long as Gemini exists and I get to enjoy it.
Wow my situations seems suddenly less complicated compares to yours :) But you are right, maybe I am overthinking it. I have a tendency to do that ^^
