I think an internal chat between Pipedrive users inside the same account would be a fantastic tool to boost productivity and sales. There is a need to communicate internally on specific matters related (or not) to activities or sales process with no need to use @comments for it as the need is for instant communication. In my case, we keep going out from Pipedrive window dozens of time per day into Whats App or Slack to chat between us only because there is no available Chat in Pipedrive. More than ever in these times, people in the same account need to communicate directly to solve things without the delay or stuffing the deals using comments (which I like by the way). Please consider this seriously. Thanks !!!
