Came pre-installed otherwise I would never have discovered it. I'm finding it a neat way of organising my bookmarks, instead of the usual list opening up on the toolbar these are icons, often using the official logo, which can be organised as normal into folders on the main screen. I use my favourites mixed on the Home folder sorting the rest into specific headings. Trouble is I have so many from the old laptop I've had to leave the majority until such time as I open them and save to Symbaloo using (another) toolbar icon. If nothing else it whiles away a dull day.
