It's great to hear that it works now!
vSSH seems to be an SSH terminal client. If you can connect with it it doesn't necessarily mean that SFTP is enabled.

The Synology SSH server has SFTP disabled by default. You can enable it in DSM.

What do you see when you are in DSM and go to Control Panel -> File Services -> FTP -> SFTP?

Here's a screenshot of how that looks for me on DSM 5.0:

Does your SSH server have SFTP enabled? The SSH authentication, but then the operation times out.

Can you have a look at the server's log file?
In the current version, a crash happens when an HTML file references other files (like CSS or JavaScript) that are not yet downloaded from iCloud. Make sure that you open all directories with the files that are referenced by the HTML file. This will trigger a download from iCloud.

I'll fix this in an update.
Hello,

you can just use the methods described at http://jquery.com/download/

The easiest way probably is to use one of the CDNs. Just make sure that you add "http" or "https" in front of the URL so that it works with Textastic's web preview:

<script src="http://code.jquery.com/jquery-1.11.0.min.js"></script>

Maybe you are referring to the onclick delay on mobile devices? You can use jQuery's tap event instead of onclick to eliminate the delay: http://api.jquerymobile.com/tap/
Hello, 

unfortunately, iCloud only supports one level of subfolders. That's a limitation imposed by Apple.
Please double-check that the URL to your .css file is correct. The file system on iOS devices is case-sensitive!
