I'm not sure about that, but would like to see a zoom tool.

chronological - note that the specific time of a plurk pops up on the timeline when you open it

good catch on the time stamp

loving the view on www.plurk.com/m/ much better - no dragging/clicking... much nicer

question was about vertical placement. Time is horizontal so what determines vertical?

Vertical is on the mobile version at link GeekMommy shared above.
