Hi,
unfortunately there’s nothing special in the enqueue system because it is already what you should do even if not using LESS files.
I like the idea of automatic enqueuing; I’ll think about it.
But as WordPress works on explicit style declaration, I’ll not hurry about this feature yet it’s totally feasible.
I wouldn’t do anything the like: one of the things I use most is the ability to include plain css files to diminish server requests, and to do that I have already to unenqueue those files.
thanks for a wonderful plugin, that I use in every single project.
PS I just wish you would add another variable to get the url of WP itself, as it would be handy when transferring sites and to write more generic code.
