SIMON BROWNE  My dear, dear SWO,

This is your fairy godmother. Your wish is granted - 10.5.2 does this and more. AND check out hot corners.  
(Version 1.1.1)

SIMON BROWNE  You can use * at any point to find all the words that start with "brown" as in "brown*". Personally I don't see the search method as lacking. If I'm looking for "brownies" I put in "brownies" - I don't want Mori to search for and find all the other irrelevant results - and if I do I use the * symbol. Once you have your folders containing "brownies", use the Jump to Next Highlight command under Edit, Find - it works very well once you click the contents of the folders.  
(Version 1.6.8)

SIMON BROWNE  Anything with Jesse Grosjean's name on it is good enough for me so I bought this before using it because I knew I would not be disappointed. Now that I have used it, you might be interested to hear; I'm delighted with TaskPaper. I use Mori all day, every day.
