I use Atom and Jetbrains editors and the above features are hard to live without once you have gotten used to having them. Textastic is an incredible app. I have look at other editors for the iPad that have the above features but they fail at so many important things like local file-remote file or publishing with Working Copy or having the ability to open an SSH Connection.
I think have Multi-Cursor (multi-caret), go to a line number and move code line up or down would make textastic virtually unbeatable.
Thank you guys for a great app otherwise.
