DELICIOUSSAFARI  I agree that a toolbar button would be convenient. The current keyboard combination is awkward. I will look into doing this in the next release.

DELICIOUSSAFARI  Thanks for the review... but not the 2 stars ;)

DeliciousSafari is the only way to create and use del.icio.us bookmarks directly from Safari. Like Pukka, it lists all your tags in a single list in the Tags folder but DeliciousSafari also allows you to select your favorite tags (see Manage Favorite Tags) so that you can easily get to the tags you use most (similar to filtering, but for single tag filtering only).

It does lack functionality that would make it even easier to use, such as tag suggestions, tag auto completion, and filtering. I will use your feedback when prioritizing new development.

As for price, it is 5 cents more than Pukka and $9.95 less than WebnoteHappy.

Thanks again for your feedback.
