Lets start with the basics: if you tap the dk (development keyboard) key at the bottom, it will redirect you to the AppStore, and there is no way to dismiss the splash screen: one has to essentially kill & restart the app. I mean, seriously?
As for syntax highlight, there is none I could see for C++, nor it seems to support automatic indent; it is essentially a very basic editor with line numbers on the left. Thats it.
To call it a code editor seems to me a gross exaggeration: maybe it works for HTML/CSS or Javascript: but if thats the case, the author should make it very clear in the description.
As far as Im concerned, a complete waste of my time.
