I just ran into this today -- I was actually making quick notes (using my QNotes program ;-)) on what I wanted in my shopping list program -- great find for me, less work!
If I had to make a few (hopefully constructive criticizms), they would be:
(1) No direct download - (but that's my lazyness

)
(2) It's an EXE, creating an installation cab in VS2005 is sooooo easy (literally a 15 second process), and it automagically lets the user
a. decide where to install the EXE,
b. places the item in the Program Files\Product Name folder,
c. adds a registry entry for Uninstall, AND
d. adds an icon to the start menu
(3) Took me a little while to actually figure out how to get a new List Item into the list (I'm assuming down-arrow is the only way). I'm going to shoot myself for saying this as my manager told me this a million times when I was a jr. developer, but I would think either a button or catching the "enter" key as well as directional-down would add to the intuitiveness of it.
Your program seems to create two identical entries in the filesystem - <listname> and <listname>.lst -- what's the difference between the two?
Anyway, nice program! I'm sure I'll get a lot of mileage out of it!
