Not sure about the other, but I keep entering my searches in the main search box (1) when looking up some emails, instead of going to the email search box (2):

Now, my plea to the Pipedrive development team: Would you consider unifying the search boxes so that, when I'm in the Email screen, it would combine the email results (1) and the global Pipedrive results (2) in a single list (like in the mockup below)?

Pretty please? :-)
