One feature that I loved on SalesForce.com was the Recent Items column on the Home page.  

*refer to screen shot below

It allowed me to see all the recent activity that I was working on.   Even had nice icons that allowed me to quickly see if it was a Contact, Organization or Lead.

PLEASE add this Awesome tool to PipeDrive.  It will speed things up for me...as right now I have to remember who I was talking too, go into Search or find the Task.
