Thanks, I'll look into it and will try to reproduce the problem.

Can you point me to some documentation or article on how I can configure this on my own network so I can try to reproduce this problem?

Is mDNS related to Apple's Bonjour?

It's not yet possible in the current version, sorry.

Thank a lot for letting me know!

Hello,

currently, only syntax highlighting is supported for Go.

It's possible to add custom code completion files. You can find the existing code completion files for HTML, CSS, JavaScript, C, Objective-C and PHP at https://github.com/blach/Textastic-Customization/tree/master/CodeCompletion

This should also work in iOS 13 if you installed a monospaced font using an app like AnyFont.

On iPad you can hide these using the "Additional Keys" setting in Textastic.
