Hello!
I've found a strange problem when I am trying to edit a file imported from the other app through "Open in". Any modification of such imported files gives me a "Cocoa error 513" and all changes get rejected. Also in app's local files menu appears new folder called "Inbox" that for some reason can't be deleted. But imported files any way go to the root of local files despite going to that inbox folder.
All files created directly in app's editor work fine, the problem only occurs with imported files.

Lately I have been using textastic as a LaTeX editor. So most of my LaTeX documents have user defined environments that I use. I have collected and made a handful to speed up my writing time. There is an odd issue with LaTeX symbol recognition with section/subsections from user defined environments using the \newenvironment{} command. As they are not even recognized. I am guessing that the current parsing algorithm does not even consider these situations. I have a hunch that this cannot be easily fixed, but I am still curious as to the likelihood of such a fix.

I will not update to iOS 5 as it will apparently slow down my iPad 1.

Is MEL support as in Maya Embedded Language? and if it is then why is there no syntax highlighting and ANSI encoding?

This would also most likely solve the synchronization of only changed files issue raised by hassan habbak 4 months ago. 

Use Textastic to write your html mails:

Allow the user to send an html file as the email body instead of as an attachment. This could be an option when the user selects "Mail File" from the file action popover.

I like your app!

I'm a new user [Textastic 4.3, iOS 5.1.1, iPod Touch 5th gen].  I'm also a Markdown newbie.

Is it expected behavior that a Markdown file containing a line consisting only of a <link></link> tag, that is separated from the rest of the Markdown text with blank lines, and with no blank spaces preceding the tag, "Generates HTML" with this tag enclosed between <p></p>?  Or is this a bug?

Also, is it unexpected that a '<' character embedded within a Markdown text line is not converted to its HTML entity?

The behavior of the second item affects the output to the Preview.
