@Sagorath Click the little slider bars at the top right of each column. You can unpin and pin columns to make them go away or appear. To add a new column that is int he top left.
@Sagorath Ok so its like this.. Home is the people you are following only, local are just posts from other people on the same server as you (qoto.org), Federated is every post from everyone in the world running a ActivityPub server (sorta).
