I have an idea!
Currently, when you want to delete or update multiple items, you have to either iterate through them or work with query builder. The query builder solution works, but it doesn't have relations by default and you need to specify table name, so I think that it would be great to have something like Repository::update. The only problem that the default repository is made for Select statements so I'm not sure if that would be possible. I can add it, but I don't know the cycle codebase well at the moment.
