I love MarkdownEditing. I personally don't like the color schemes that come with it; I prefer my own custom color schemes. I have successfully specified my preferred color schemes in MarkdownEditing's User Prefs, but to switch back and forth between my custom light and dark themes now requires (as far as I can tell) editing that User Prefs file manually. It would be wonderful to be able to specify a MarkdownEditing User Preference to use whatever ST3-wide color scheme is currently selected.

P.S. I am currently extracting the MarkdownEditing Package, and commenting out the color scheme lines in the .tmTheme files, but it's a minor pain to have to do that every time the package updates.
