Seriously? Can't preview? – Buffer Editor - Code Editor Review

I want to be able to use my iPad Pro as my main machine. That includes being able to write in python and then test/view it. Having an editor but no preview? Waste of money. There are free apps out there that let you "edit". Let alone this app calls itself powerful, can't zoom in on text to make it comfortable to view, doesn't include OneDrive connectivity, github pull/commit? Doesn't work as advertised.
