What's not working with XHTML for you? Just the preview (this should work in Textastic 2.0) or do you have problems with the syntax highlighting?

The "HTML" syntax highlighting definition should work for XHTML as well.

If you have problems with a particular file, please send the file to support (at) textasticapp.com so I can reproduce it.

Oh, and you can select XML syntax highlighting for SVG files by manually choosing it in the "File Information" popover for now.

If it doesn't work for you in Textastic 1.1 then it's probably the same issue as with php files: see http://feedback.textasticapp.com/feedback/8060-web-preview-of-php-files-doesnt-interpret-html-part/ – I've fixed this in Textastic 2.0 which is currently in review at Apple.

I'll add the svg extension to the XML syntax definition for a future version.

Thanks - and the German was nearly perfect, danke ;)

The article at http://stackoverflow.com/questions/2936326/what-is-the-difference-between-erb-rhtml-and-html-erb seems to confirm that.

I've added the erb extension to the rhtml syntax definition.

I've added a "Read-Only" editor setting to the app's settings.

I implemented #2 for Textastic 2.0 because I could use the same interface as for the FTP client.

This is implemented for Textastic 2.0:

I added a "Move" button next to the "Delete" button that will allow you to move files and folders to other folders.

It's also be possible to rename and copy files and folders.
