Improvements for Contacts App

I have a small Idea for Speed Improvement in the Contact App. Loading my 200 Contacts on a Raspberry Pi takes some time. I think, it would be better to load them in Chunks. What do you think, if we load only 30 or 50 Contacts and load the rest if we scroll the list to the bottom and reach the end(next 30 entrys)? Additionally, the Counter for all Contacts should always visible, not only at the end, maybe this could be done, if the Contactlist ends above the Counter. Any chance to get this in a upcoming version?

BTW: The value for Chunk-Count should be configurable.
