This is mainly an issue with large files.

When device rotation occurs, the page position changes due to many lines becoming wrapped (or unwrapped). This in itself isn't a horrible problem, but what tends to happen is this: 

I am at line 5500, the file is 6200 lines. 

I rotate to portrait. It pegs me at the bottom of the file. This clamps the y-offset.

Now I rotate back to portrait in hopes of returning to line 5500. I am dropped off around line 4000.

This is... not... ideal. 

One great way to fix BOTH issues is to check the line# and return me to that position upon device rotation. 

Note also that having a cursor present will prevent this issue (which is probably why this has not been reported yet). However having a cursor makes over 1/3 of the screen consumed by a keyboard so I *ensure* the keyboard is put away when I use Textastic to read code (as it's hardly practical to do actual coding), but it causes this issue every time (when i am near the bottom of a file).

So since I am JB'd i would use tweaks that let me force specific apps to be portrait-locked, but it's just not ideal because sometimes I do need to go landscape when the line wrapping gets to be overwhelming.

For switching quickly between files, example, I read a plist I created representing a default value array and I wanted to write it into code. Since its a large plist I need to switch back and forth from the file to the plist

I think it would be great if you added support for PAWN. If it was added, I would purchase this app in a heartbeat. I use PAWN to work on SA:MP servers. 

Can the font size on the ipad be adjusted?  I have poor eyesight and will have to enlarge the font.  A fallback solution is to buy the iphone app and then click 2x.  What do you recommend?

Working copy is a source control app released about a week or two ago. It allows me to commit files to bit bucket and if your app was in their share sheet or displayed in the share sheets available to them, I could edit the files in your app instead of their crappy editor.

My sample has 3 files: index.html, screen.css, and screen.js in the same directory. The preview shows my styled html but the javascript will not run. Checking firebug lite script>inspect screen.js shows in the dropdown but the script window says "Access to restricted URI denied". The javascript code runs when I export it using Dropbox elsewhere so I know it is accessible and working.

It would be really cool if textastic doubled as an interactive python interpreter with a command line function and everything. Since python doesnt need compilation i believe it is possible. Thanks!
