it would be really great to have a lemmy client (or feature of existing client) that allows for batch downloading of a user specified list of communities.
this would allow a user to download all the content for the day or week on wifi internet and then depart from the source of internet but slowly & carefully read a selection of material(text posts, comment discussion, and even images like memes).
one benefit is that it would be extra impossible to see what users are loading/viewing because they already loaded everything and are disconnected from the internet entirely. performance is also good because there is no network latency that would be experienced, each time, when accessing the servers.
