Hmm, well, the same thing with SublimeText3 it asks for a reload but inhibits editing once the file has changed on its own. So, I just unload the skin edit then restart.
You did see what happens though - the skin broke for you and would not work. Therefore you do know what I meant when I said there are 'issues' with editing.
At any rate, NP++ or PN3 or ST3 - I've used them all as well as others for editing several languages, so I know they all have different behaviour with 'live' editing. I like ST3 the best since it is the most configurable and I have indeed configured those all to some degree.
Thanks for the assistance, with this thread's topic as well as many others.
