Lower left on the windows client below projects. I clicked the x to close it. Now I've right-clicked and also searched everywhere in the program but cannot find a way to turn it back on. On the web client I just click view and then "mini-dashboard". But on the Windows client there is no view menu nor any other obvious method I can see to turn it back on!
Edit: found it - "toggle the mini dashboard". I kept looking in the menus or on the project sidebar.
