Tinderbox 1.1 (coming soon) lets you drag links (and bookmarks) from you browser and drop them into your Tinderbox window. The new note is automatically given the appropriate name. Its URL is the URL of the link you're dragging. And it's set up to ViewInBrowser, so it works just like Web Squirrel: double-click and there you are. (Plus, you've got a place to take notes, and you've agents, and Autofetch, and more)
What really helps, though, is the extra size of the TiBook screen (and the Cinema Display, for that matter). The extra pixels give you plenty of room to keep a Tinderbox outline open right beside the browser. Very handy.
