Nevermind - I changed the behavior so that this now only happens when the document is a draft/untitled document and not saved yet.

It will be fixed in the next update.

Thanks. Another user recently reported a similar error. Do you have Auto Save enabled or disabled? (see http://osxdaily.com/2012/08/22/turn-off-auto-save-os-x/)

It's registered as a secondary viewer for all files so that it is able to open files with unknown extensions. This has the side-effect that it's also shown for image files. If I disable this, you lose the ability to open a ".mycustomfileextension" file in the app. Coda probably does the same.

I think I could disable it for image files. I'll see what I can do.

Voice over is now supported for the main text editor in iOS 6.

Yes, since iOS 6, Textastic has good voice over support. See http://www.applevis.com/apps/ios/productivity/textastic-–-syntax-highlighting-ftp-sftp-dropbox:

*** UPDATE ***
As of December 8, 2012 this app is accessible on the iPad. I am now able to navigate the text areas as I would any other document in IOS. I wanted to leave the original negative review hear to give credit to the developer for finally making this excellent code writing and management app accessible.

Danke! Beim letzten Video konnte ich es jetzt gerade tatsächlich auf meinem Macbook Pro nachstellen! Seltsam, dass das vorher nicht geklappt hat.

Aber nun hab ich einen Anhaltspunkt, an was es liegen könnte. Ich versuche, das Problem zu beheben!

Und ja: Tabs sind Top-Priorität - das vermisse ich selbst auch am meisten.

Yes, if you tap and hold them. 

You can already do that using either the action button in the top right corner or by tapping and holding a file. ("Send as attachment")

By the way: I did follow the steps and it is working just fine on my Macs...
