Nice addon - love the simplicity. Just repeating the request for these features..- ..they'd all be incredibly useful.
- editable SlimSearch menu (enable/disable entries, add/remove entries, change menu tree structure, change order)
- allow it to use regional search engines (e.g. Froogle UK)
- pretty menus, maybe with icons (+favicons)?
- enable SlimSearch to do searches on text selected in text entries in forms
- enable separate slimsearch menu for use with an activator key (ie; Pressing Alt or Cntrl while double clicking/highlighting a word brings up the dedicated slimsearch menu)
