are there any plans to add any kind of dynamic resolution of CFC's / function definitions in this new VSCode plugin ?

You can use the Adobe CFML and the CFML (by KamasamaK) extensions at the same time and get dynamic resolution of CFCs and function definitions.

That'll be nice. I wasn't sure if they'd fight each other. I already miss some of the features of the CFML extension. Ctrl + / for commenting out comments, etc.

It'd definitely be preferred to have the Adobe CFML extension do it all though.

Absolutely! I read through the PDF documentation. Don't see any mention of keyboard shortcuts. All the links in the extension description are still broken, so can't read that yet.. A code formatter on save would be really useful too. I already use a commandbox script to "cfformat" on save, but again, just another thing that could be added to the official one.

so far my impressions are pretty rubbish and the sublime text ColdFusion plugin is still a much better editor for CFML

You can see the keyboard shortcuts for the commands that the extension contributes in VS Code's extension view under "Feature Contributions".
