Clicking the line number would add a bookmark to that line (visible by highlighting the line number somehow). Then a keyboard shortcut or popup window (maybe a couple icons added to the Line Number and Column number window?) would be used for navigating to First, Previous, Next, or Last bookmark (or just Previous and Next if there is not enough screen for four buttons). These icons could be hidden if there are no bookmarks in the open file. Clicking on the line number of a bookmarked line would remove the bookmark from the line.

And return to it when switching between files

When editing i usually switch between two or more files and it will be great if cursor will stay on previous position when switching

A lot of my code is minified and makes it almost impossible to read using this app.

I usually just use the code formatting option in dreamweaver then minifiy it when im done.

So, I guess I am requesting 2 options.

1. automatic code formatting

2. minify code option

I accidentally deleted the contents of a significant file - and then switched to another file. I lost the work in the first file because undo history resets when switching way from a file. Can undo support be more enduring?

Add iOS 4.2 fast app switching, background saving (and future uploading/downloading?) support.

4.2 is due until next month, but it doesn't hurt to already implement it. Also, I'm already on the beta. ;)

Please consider  adding jquery/jquery mobile code completion support.  I plan to do all my iPad  app development using TextTastic!  It is a brilliant tool.

For security reasons, some people don't want to save passwords for connections on their mobile device.

Instead, Textastic should present the user with a login dialog to enter user name and password when it is first trying to connect to a server.

Pages shows a popover when you tap-and-hold the undo button. Implement the same in Textastic.
