a lot of file extensions are not associated or having the option to open them with textastic app using Files/iCloud/OneDrive/etc..

Please add the ability to edit any text based file extension from there.

When I add a new FTP I'd like to be able to use 1Password.

The JavaScript support is already great, but help with the jQuery functions would be a big time-saver as well.

For security, Textastic could cache opened files in local storage.

While browsing in FTP server, tapping in a single button right in the file name would open it for instant edit. So, user would make any changes and then, tapping in "Save" button, that opened file would be instantly uploaded, without confirmations, easily and faster.

That feature are present in many SDKs and similar softwares like Coda (i use that one), and I really wish Textastic could have this feature soon!

Your app is amazing, Alexander!

Congratulations!

It would be great if you could implement something like cocoa http server instead of using a file path so when we're building web pages we can use the likes of less, angular, backbone which all currently won't work because of being a file path protocol and not a local web server.

To clarify further, having this ability also gives us the opportunity to have something similar to Codea's "Aircode" and to run Ajax requests in page, it will throw a security error at the moment because of not being a http protocol.
