How can I setup Textastic to SugarSync account?

I saw a comment from a year ago with planned support for UNIX file permissions.  Anywhere in sight yet?  I don't even need to change the permissions, but when I sync a folder with Bash o Python scripts which are executable in the Mac and edit them in Textastic they loose their executable bit, which is not nice, specially since some of them need to run from a cron job... It would be nice if you preserved whatever file permissions where there to begin with.

This is driving me crazy.
On my IPad Air, I edit files on a server using the document picker and Transmit (sftp connection). So far so good.
I have a second iPad where the same workflow doesn't work: I select the "Open.." Menu, then Transmit as file provider, the connection is established, I can browse the files on my server but when I want to open one (whatever the extension) I get the message "The plug-in returned an error. Could not connect to server xxx." Please note that the server detail are the same on both iPads as they are synced with Panic sync service.
Beyond the fact that an identical workflow works on the iPad Air (same versions of everything), the crazy part is that:
1. If I use a different file provider, e.g. Working Copy, it works
2. If I use a different text editor, e.g. Koder, it works.
3. If I offer the file to Textastic from Transmit, it works.

Of course I have tried to reboot the iPad, uninstall/install both apps, with no effect.
I also tried the same workflow on the iPhone: it doesn't work as well.

Has anyone any idea of what is going on? I found no info search for this problem on the web.

Great product, but it would be nice if I could directly access files in my dropbox (edit/save directly in dropbox, without having to launch dropbox app, browse to file and open in textastic, rather browse dropbox account directly in textastic)

Also, it would be nice if you added native support for Flex 'MXML' files, the syntax can be relatively the same as HTML/xml/as with very minor modifications if any, however direct support for .mxml files would be great.

For those us using Objective-C and C/C++ placing the ';' and ':' keys near the braces and bracket keys in the top row of the keyboard would make for better flow and productivity when typing.

MultiMarkdown, pandoc, and other markdown processors support definition lists in the style:

Term
: Definition, starting in the fourth column

I would love to hvae this added to textastic. Actually , since my workstation-side processing is in pandoc, I'd be thrilled to have perfect mimicry of pandoc-style markdown: footnotes, tables, DLs, math.

It'd be nice to have syntax highlighting for Makefile, but more important, if soft tabs are enabled Textastic should disable them if a Makefile is being edited (Makefiles must use tabs for indentation). Sublime Text does this and it's a life saver.

The code completion list looks bad in Textastic 4.0.1 when running on the 3rd generation iPad.
