WTH is the standard logbook and history time span

I’d like to be able to configure what the default time span is when I open the log book. Same for when I view a history graph.
I’d like to be able to set this per type of entity, per label and per specific entity. I don’t know yet what the default length should be, but I know it’s not the time spans currently in use, because I always have to change them whenever I open a history graph of an entity or the HA logbook.
