I have bought Textastic for a few months, and I feel good (I use it mainly for C / C ++). But the only thing I regret is the lack of the minimap. As it allows you to see the code structure and go immediately, in a code section and change it. Although it may not be available initially for all templates, but at least we could appreciate this features in an excellent editor.
Thanks a lot,
