Hello author, I have found a difficulty in using farsight-1.16.5-1.7.

The farsight worked well when I was running around in the server, the client rendered distance could be much larger than the server view-distance, but when I teleported to my home somewhere else, the rendered distance became the same as the server view-distance, which meant I needed to run around again to get a more distant view in the game.

Perhaps by having farsight recording and storing (in .minecraft/.xxx) all chunks sent by the serverwhich it then can load and display at a later point when the chunk is outside the server's view-distance.
This is what I saw from Bobby and I thought maybe farsight could do the same.

I intentionally do not save chunks to disk and load them, as that comes with a bunch of problems so I'd rather keep this functional and lightweight.
By default it keeps chunk data in 32 chunk distance(similar to render distance = 32), so yes if you move too far it will forget the data. This is intentional to keep the memory usage on a normal level, but you can increase the distance in the config to sth big if you really want to keep that data loaded forever.
