I have installed the latest version of Redmine. Our need is to make redmine support project management activites just as some of the other famous management tools do. Could someone please suggest some widely used plugins for redmine? Is there any plugin known to have pop up notifications, chat application, and make the redmine real time, without having to refresh the page?
I also plan to develop some functionalities from the scratch, Do redmine has REST API, which I could use, and how can I connect to Redmine REST API.
