@Gargron One thing I would like to see is a default block of hate and bigotry, something that users can choose to implement or not, something configurable. Or at least up front info on how-to.
New folks need a wee bit more hand-holding and not the assumption that they 'just know' how to navigate the #fediverse, and being able to preemptively block things (or at least be given the knowledge on how to *when they join*) would save vulnerable people a lot of grief.
