I found this post on SU, but it doesn't seem to address my needs exactly, so I'll ask a similar question. I normally use PSPad, and I'm also not too scared of Notepad++. They are both good editors, but their CSS highlighting seems to be lacking all the CSS3 goodies.
To top that, I recently started using LESS instead of plain CSS, and this is where both editors fail miserably. As soon as nested properties are encountered, PSPad gets completely lost and is unable to even show matching braces, not to mention bad syntax highlighting. Notepad++ is somewhat better, as matching braces are always shown correctly, but still, nesting makes Notepad++ lose its way around LESS.
So, do you happen to know how I can make either of these two cooperate with LESS correctly? A downloadable resource will be fine, or perhaps a plugin, if you know of one (I don't). Alternatively, if you know of any other good lightweight editor that can offer good LESS highlighting, please point me to it (and please, no Eclipse-based stuff, it's way too heavy for just a CSS highlighter).
[Edit, in case anyone finds it useful]:
Since writing the question, I have come across a great, albeit Java-based and thus slightly sluggish, IDE. It's called PhpStorm, created by JetBrains. As I use it now for most of my PHP coding, I also end up editing LESS files with it. And here comes the surprise: PhpStorm has out of the box inbuilt support for LESS! It's not perfect, as it sometimes forgets to display autocomplete suggestions, but overall it's really decent. Like I said, it's not a lightweight solution, and not free of charge either for that matter, but I use it for all of my coding nowadays and find it very recommendable.
