To activate the upload button, you have to tap on a remote connection so you are connected to a server in the "Remote" side of the File Transfer screen and there must be at least one file selected in the "Local" side of the screen.

You can either open a local file and tap on the action button and choose "Download Latest" before you edit it or you can go to the remote transfer screen, connect to Dropbox and download the folder again overwriting all local files.

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.
