WordPress.org

Does this support multi-line enclosed tags?

YES! The main reason I wrote this was because I have documents where an opening [b] tag might be several paragraphs up from the closing [/b] tag, and this caused other plugins--especially shortcode-based ones--to puke and produce no text at all.

Will you support YouTube tags?

If someone asks for it. I assume there are shortcodes that already do this, though.

Can you support random tag [x]?

Sure. Just request it in the comments here: http://www.gorzek.com/dev/wordpress-dev/bbcode-filter

Please describe the tag and what it's supposed to do. I mostly want to support commonly-used BBCode tags, so try not to suggest anything too outlandish.
