Usability suggestion for the Universal version of SF: if you, for example, [Ctrl]+click on Subjects under User interface, a new instance of the Subjects screen opens. However, doing the same on Subjects under Open documents does nothing.
Because of this, I have to look up the Subjects option again under User interface, even though I usually want to open a second instance of a screen at exactly the moment the first one is already open — and therefore already shows up under Open documents.
Please make [Ctrl]+click work under Open documents as well.
