After getting everything organized the way I want, it would be awesome to resize the window (or use a hotkey), have the left pane collapse, leaving just my right-hand-pane project or Focus list. Optional setting for always on top.
Things 3 gets this perfect. See the attached screenshot.
Yeah. I want something small that I can keep in the corner of my second monitor while I work. When I resize to minimum size, Everdo still retains its LHP navigation widget. If it would automatically collapse once the window was resized under a certain size – like Windows UWP apps or Things 3 – it would be perfect.
