Good riddance. Coda for iOS never worked correctly and was a scam app. It's utterly unjustifiable that Panic sold a "full-featured" editor that only works on "Sites" and not files.
That's a horribly irresponsible thing to say.
Panic charged me $24.99 for a full-featured code editor. I would like a full-featured code editor or I would like my $24.99 back. It is not "horribly irresponsible" to expect what one pays for.
