Nix the whole EgretList app route...while I enjoy the UI, it's too much of a hassle if you want to move the db around as it is locked to the device you configured it on (so that means you can't migrate your stuff to a new device when you upgrade).
I ended up using the Smart Folder solution with OF and it works great...now if we could just somehow get he RTF notes from Evernote to display in OmniFocus, we'd have a solid referencing system of sorts. :)
Think I might have posted about that somewhere else... How were you using EgretList exactly? For general reference material? I'm finding it very useful specifically for checklists that need re-using (and I put in a feature request with the dev to have one-click check/uncheck all).
