Feature request - intergrate popup markdown selector from quick notes app

feature

#1

I really am starting to enjoy using MarkDown, and very much like the double pane view the MarkDownEditorApp is providing. You can see result as you are creating and editing your content.
Also liked the popup markdown picker from the QuickNotesApp.QuickNotesPopupMarkDownSelectorScreenshot2018-11-16_18-12-31 As soon as you select text, it hovers just above that text.
Would it be a lot to of work to intergrate the PopupMarkDownPicker into the MarkDownEditorApp?
Thanks for your time and consideration!
