I tried that, but missed the Evernote View -option (or it was not yet implemented)! This is perfect! One thing could make it even better, though. If the whole folder name line would work same way as the click to the plus-minus-sign. So if I press folder name, it will reveal files in that folder (or optionally files in subfolders, too, as it is already implemented) AND it will also reveal subfolders in the upper folder pane. Clicking the name of the folder again will do nothing in the lower pane, but will close the subfolders in the upper pane. This would be cool since now if I want to see files of the folder in the lower pane and subfolders in the upper, it will require two clicks (and plus sign is smaller target that the whole row :))
This plugin is excellent as is, though, and makes file explorer significantly better than the original. Have a good coffee!
