To get the Heart icon back, type the following in Terminal and relaunch CoverSutra:

defaults write com.sophiestication.CoverSutra gender 'female'

For a shiny heart, check my mod out:

For those lamenting the loss of Growl prefs and/or gawking at CoverSutra's RAM usage, check out the Advanced Preferences by holding Option down while displaying CoverSutra's menu from the search bar or menu icon, as shown below:

Disabling "Automatically reload library" may ease your CPU / RAM woes, I'm not quite sure myself as of yet.

KOHLMANNJ  Delimport is an excellent application that provides someone with a large number of del.icio.us bookmarks, such as myself, with absolutely seamless Spotlight integration. The application imports your del.icio.us bookmarks using the del.icio.us API and produces a local cache of them, allowing Spotlight to return your del.icio.us bookmarks as search results.

A QuickLook plugin for delimport's bookmark files that displays each one's appropriate information would be greatly appreciated. I look forward to the future if this is only release 0.3!

Highly recommended for anyone who uses del.icio.us and a Mac.

KOHLMANNJ  SVG Detective did exactly what it's supposed to do for me - I opened an SVG file and was able to export a PDF without any hassle whatsoever. That said, it's something of a one-trick pony, but for that trick, it's a very handy little app.
