Give the Leads tab at least as much functionality as Contacts. TBH, I don't really see a use for Leads the way it is. I uploaded a spreadsheet for one of my sales team members to make some calls through Justcall. I made a test call and as soon as the call was over, my lead disappeared. I had to go hunt for it (not the best use of my time!!!) A spreadsheet is better than this feature at this point. I then deleted it and put it as a contact so my sales guy would not waste time doing unnecessary admin work.
