Multiple follow lists is also an option. Then you can have a high priority list and a second lower priority list for when you have more time to fill but completed the first list.

Is there actually a way to do that? Like already made?
Listr. Amethyst also supports lists.
There are tradeoffs. I haven't implemented this myself though I plan to. It is better that multiple nsecs because lists allow to to easily reply from the same nsec instead of switching accounts then needing to re find the post you want to reply to.
