Really only interested in something like Graphene, Lineage, or a Linux mobile tablet that can work with a typical Linux distro and display over USB-C. It is just a casual conversational ask. Maybe one of y’all has tried or knows the answer. I won’t use anything that runs google stuff or is a pain to load a custom ROM.
You can sort of do that through the starring system. At least, Thunder lets you star posts and comments for later. However, if you use it also as a way to track favorite submissions, then they’ll get intermixed.
Reddit also has post-saving, which I think was implemented around 6 years ago or so (I’ve been on there for a while lol).
