Wow, the not-stretch-across-the-screen thing really is quite nice, isn't it? (It's nesting things in the other direction that's merely annoying.) Though personally what I'd really like is secret tags that stay inline, so that if I just want to hide one word in my sentence, like
Click here to view the secret text
×this one
, the paragraph doesn't look stupid.
(That happens a lot, too, like when you want to say "
the trick to 1N1E was
killing the adder first, which took me ages to realize"
and really only want those four words in red to be secreted.)
Clearly the solution is to have a new tag, [sekrit][/sekrit], that does this.
