Since upgrading to Coda 1.5, code completion has been hit or miss for me. When linking a script to the document it will stop auto completion in the middle of the tag. When adding a comment in HTML it use to give me a choice when I would start typing, now nothing.
It's not a big deal by any means, but it was a handy thing to have around.
The Code Completion in Coda works beautifully. However, when editing CSS within an HTML document (which happens sometimes) the CSS completion does not kick in (obviously because I am in an HTML doc). I understand - but it sure would be sweet if Coda could recognize the style block and offer completion for CSS within that block.
