As for the Chrome extension, I had to use an alternative one, because the official one cannot be configured to have a single click to save - it shows up a menu from which I always need to pick one of similarly sounding options having to do with saving. I'd love to be able to disable the features I don't want, and have the tool lead directly to save if that's the only feature I have left working.
As for the mobile (iOS), the situation is really bleak, as most of the iOS apps seem to be abandoned, and the only one that seems to work fine for saving (Pins) has a weird way of syncing that only syncs up some number of latest pins, and then only being able to offer tags that are among those. This results in the app not offering the tags I am sure I have, and me mistyping them, and then making a mess in my tags.
Tbh, I have multiple times considered spending a day with Cline/Cursor to make a simple save-only iOS app, but then I always thought - wait, isn't that what I am paying a yearly subscription for?
So, for me, paths to saving (= main use case of Pinboard for me) are clunky on both browser and phone I use :/.
I don't want to hate, but talking in Kano model terms, while I really appreciate Pinboard being a stable and reliable service, over time these paper cuts shifted from nice to haves into a missing basic needs, which cause me to look into alternatives.
