Can you please elaborate on that? The editor only changes the zoom level, when you use a pinch-to-zoom gesture. You can also change the font size and word wrap position in settings if you want to permanently have another size.
You can just open another file. I didn't want to waste precious screen real estate for a close button.
I will add the xslt extension.
Of course! I just wanted to explain why sftp probably won't make it into the app.
This is implemented in the next update.
