Center + fit timeline vertically
When expanding/reducing track sizes or adding/removing tracks it would be useful if PP had an option to 'auto-fit' the timeline to the vertical space.
If you look at the way Avid deals with it you'd see what is possible.
(Obviously expanding too much and something has to go off screen)

This is an excellent idea and I believe can be done in Audition, so please bring it to Premiere Pro!

Avid tries to keep the timeline centred & visible when zooming tracks vertically - PP keeps current position (which means zoom bars are required more readily).
(Also Avid does not require timeline tracks to match the source tracks to be able to display the source tracks for patching).
