Rated 5 out of 5 stars
I can finally get my search results unthreaded and sorted the way I want, with zero clicking! Definitely 5 stars for making this possible.
There are some rough edges, the options dialog isn't super clear but gets the job done. Disabling the threaded view only works if you select the "Thread" column to be visible - a bit funny that it has to be visible in order to make it redundant, but hey, I'll accept anything to get rid of the threaded view!
Kudos to the author who fixed a small issue pretty much the same day when I first reported it.
Romkyns coming through again. I've fixed the 'disable thread only if visible' problem, expect v2.1c soon. Also, you can now sort by columns that aren't visible (which seems weird to me, but I suppose it's better to make everything possible).
