Well, as one of the "early adopters" of Google's Notebook, I was sorry to see that it was about to be discontinued. Hats off to Google for the idea of Notebook, but, though Google had seemed to keep adding new/improved features, I always found the thing a bit kludgy - and it had a poor response time. My use of Notebook therefore faded away, and finally went to nothing after I started using Scrapbook to save my precious stuff to my laptop's hard drive - I often want access to my stuff offline.

The suggested online alternatives to Notebook might be all well and good, but because I often want access to my stuff offline, Scrapbook is just right for me.

I'm not sure, but I think you may find some freeware that does this already:
e.g., mp3DirectCut, MP3RepairTool.

Reading the post about deviantopian's To-Do Tree (I didn't try it, but it looked nifty) made me think of something else.
What started me thinking was the screenshot with that "sidewise tree" hierarchy view - it was redolent of the Lotus Agenda "Category" tree, and made me realise (again) that when someone has an idea they will generally be surprised to find that it has already been invented.   :(

Lotus Agenda (currently available as DOS freeware from IBM) - now THAT would be an application worth emulating by Donation Coder. It was a super-sophisticated free-form PIM + text database, that just happened to be useful for To-Do lists, amidst lots of other things.    :-*

Anyone in Donation Coder up to the challenge of recreating Lotus Agenda? (Don't say "Chandler" - that's nowhere near like it, and never will be, given the rate and direction it is proceeding in.)

I reckon that if you can come up with a find-and-run like FARR (which, imho is nothing short of a brilliant piece of work), then you might have the capability to do a leapfrog over Lotus Agenda and bring it to Windows if you so wanted. What to use? XML, or SQL, or maybe...hmmm - so many choices! If you do decide to take up the challenge, then please feel free to use me as a ß tester. I used to be a Lotus Agenda uber-power user, so was familiar with most of its features, constraints and limitations.
