Right click on a project in your drop down menu and open it in a new tab. This will make sure that your current project is still open on the old tab so that you don't have to click your way back to the previous project all the time. This was possible before but is not now.
Thanks for your feedback! Right now this is not something we can prioritize. If you are on "My overview" you can right click on the projects you find in the Work space list. Or you could also just simply duplicate the Projectplace tab and search the project you want to open.
