I suggest "collapse the right rail while in source mode" is collapsed by default. In source mode, most of the vertical strip is pretty much useless.

Also, source mode tend to be "draggy" when it is trying to auto-complete on my computer (i.e., when type "[[" or "{{" ). It comes to a point where I find it easier to just work off a notepad, then copy and paste it back. Is there anyway to disable it?

As with the previous editors, Visual mode also gets disabled if there are nested templates... "somewhere" in the document, even if majority of the elements are "non-complex". It will be nice if the offending ones are just encapsulated like any other "code elements".
