Requesting implementation of Shiichan's comma syntax to refer to well-defined sets of certain posts.

I was nagging MrVacBob into implementing that. Needless to say, it will be in the next Kareha version too.
I was surprised by the backwards ranges (ie. 15-10 in the link above) being valid and listing the posts in reverse order. Not really a bad thing, just unexpected.
I've been thinking of more extensions to that. The only useful one that I can think of is 'qX', which would display every post with an anchor to X. That would be kind of slow, though.
