multiple selection
You should add multiple selection tool and column selection tool to textastic. I use this tools on Sublime Text, absolutely great tools! I bought Textastic for both of mac and iphone, great app, congratulations.
git integration
I'm a Bit Bucket user and there are a ton of Github users out there. Git integration would be awesome!
Emmet (Zen coding) a must have for HTML/CSS work
I'm really missing Emmet (Zen Coding) functionality.

Highlight selected word in document
From Notepad++ and Eclipse I love the feature if you double-click on a word (or select it) and it automatically highlights every other occur of that word in your view.
Would be really nice to have that feature in Textastic!
block indent / unindent
It would be nice to be able to indent a whole block of highlighted code to the left or right. In IntelliJ, this is the <tab> or <shift><tab>. I find this very useful!
Actually, that's already possible. Have a look at the "Text" menu: Shift Left / Shift Right commands.
Selecting text and pressing Tab and Shift-Tab works, too.
Block editing
Being able to edit multiple lines simultaneously and/or multiple text cursors. (Like Sublime or SubEthaEdit).
Save window size for individual files and reopen them with the same frame
Title says it all, would be nice if the window size stays the same when reopening a file.
