Tiddlywiki in Documents App for iOS: How we could save?

[Dino]

Dear Sirs, 

Since January, I've been using the Documents App in iOS (iPhone and iPad) to read the Tiddlywiki files. 

In this application, you can sync an entire folder with Tiddlywiki files and sub-embed-files (pdfs and images), and you can access the content without problems. It is a kind of self hosting in your personal device.

Did someone try this application before?

The only problems I have is that the TW file can be read but I can't save (as in the TiddlyDesktop).

You can save and download to override the file, and sync the folder. 

But I would be glad if we could save the file (as in the TiddlyDesktop). 

Could the TW offer some kind of save support for this Documents application?

Yours,

Dino
