Pipedrive integration there but it has several flaws and it is hardly usable so it would be great to implement some improvements:
  1. now it shows all the deals associated with the person despite its status (won/lost/open) and if person has/had 50 deals it would show all of them and the button to add new is at the very bottom, so you should scroll all the way down. It would be better if add new deal button would be at the top. Then it should show only active/open deals (or at least show Top 5 recent deals) and all other deals should be expanded only when needed. Same applies to activities and notes.
  2. another great feature would be possibility to link conversation to specific deal and use pipedrive deal's BCC address to automatically forward and assign email conversation to specific pipedrive deal.
