You can find the latest code completion files at https://github.com/blach/Textastic-Customization/tree/master/CodeCompletion

These are supported at the moment: HTML, CSS, JavaScript, PHP, C, Objective-C

For CSS, code completion of properties like "border" or "background-color" should work.

There is no code completion support yet for C#. I fixed a bug in the latest version that showed C functions and code completions in C# files which was wrong.

It works just fine for me. I opened the "GettingStarted.textastic" file (which is a Markdown file), entered "<" and a list of html tags popped up.

Hello, yes, you can't move a file in the folder were it already is, hence the error. I'm not sure how this is a bug?

Hello,

which SFTP server are you using? I've heard about this problem before, but it works without problems with my own servers.

It will be fixed in Textastic 4.2.2

It was added in version 4.2.0.

Hrmm, maybe I read your post wrong. Did you first upload or download the file from or to Dropbox using the file transfer screen ("globe" button)? The link is established by uploading or download the file. 

It's explained in the manual at http://www.textasticapp.com/v4/manual/lessons/How_can_I_quickly_upload_downloaded_files.html

If you want to know how to move, copy or rename files: http://www.textasticapp.com/v4/manual/lessons/How_can_I_move__copy_and_rename_files_and_folders.html

Did you move the file after you downloaded it? If you move or rename a file, the link to the remote location is lost.
