if I can customize this list in latest versions, I am probably not aware about it!
But I create many lists on-fly, just sorting the newly discored acounts of lists. Some of these list are pretty hamless and would provide good "starter packes", which can be mass-followed by anoyone on instance (but also hidden from main timeline, perhaps). I mean groups like "Nature photographers", "City photographers", "Generated art", "Travellers", "Hikers", and so on - there are many accounts, which really provide just one type of content and can be easily categorized.
As instance moderator, I am getting lot of feedback, from both new and more experienced users. New users find it hard to find any interesting content to follow: we don't want algorithm, so creating named specialized lists manually may be the other way?
Also users requests chance to tune the timeline. There is already "hide list" feature, I use it to mute too much active accounts. Other users request feature to hide boosts and to see only original content (perhaps could be also property of certain lists? just like hiding, but hiding only boosts?)
