It would be marvellous if the plugin would somehow use the Sublime Project root as "/", because it's often the case that my CSS files are in /css/ and my images are in /images/, and all of my references to files in CSS are absolute paths. So instead of background: url(../images/bg.png), I use background: url(/images/bg.png). In this context, the plugin is of no use
Also, is there some way to have the auto-complete window make suggestions immediately as I type, rather than after a manual invocation with CTRL+SPACE? It was also unable to complete a filename if I began typing one that I knew already. IE: ../images/backg[CTRL+SPACE] yields no suggestions, even though I have a background.png image in there.
Just thought I'd post my feedback! Thanks for making this
