This is not worth it

I get that you want people to buy the in-app purchase to enable all the features, but the reality is, the go-to code editors on iOS are GoCoEdit, Textastic, and Coda. If you have something that makes your editor unique, show some effort in promoting that. But as it stands, this app is currently worthless.
