When working under Windows I can open as many MATLAB instances as I want (and instances of other Windows applications as well).
Can it be done with PyCharm?
I can't open more than one for now.
Go to File->Settings, Appereance & Behavior -> System settings, than find line "Open project in" and set "Ask"(Settings window screenshot), now you can File -> Open recent, and you will get ability to open another project in another window.
