Here's one "extra mouse click" issue that I'd like to see resolved:
When clicking from another app (say IE) into MC, I like to click directly onto a property value and have it be in editing mode. This doesn't consistently work. Sometimes, when clicking from another app window onto any property value, for instance Date, it switches from editing to not editing mode very quickly, and I have to wait a second and click the value again to make it edittable. I often want to do this to paste values from other windows, and it can be a pain to have to click twice, but strangely only sometimes.
An example to replicate this(I'm guessing there is an easier way, but this is how I encounter it): Open a browser and tile the window such that you can click back directly into the MC property pane, then return to MC, go anywhere in the media library, and select any song from the view pane, then select artist info from the toolbar - might need to add it, which brings it up in the external browser (the other way I know to get the artist info is to click Artist Info under the Tree view Playing now, but that seems to bring the browser up inside MC, which is not what I want because I don't want to have to click Back several times to get back to my media library view).
Now, click back into the Date property value, and it should flash for a second as editing mode, then switches to "Not editing" mode.
I think it would be more consistent for the property values to always be in "editing mode" if direcly selected after coming from another window.
