Squirrel - Version 1.0 Squirrel stores notes in a hierarchy whose structure you choose. You can easily paste information from other applications, and quickly search the note titles and contents. Paste Web addresses using the taskbar menu or with Squirrel’s auto-paste facility (copy to the clipboard twice); and if you're using Internet Explorer, any title, description and keywords associated with the current Web page will be inserted into Squirrel along with the address, for off-line searching.
