I would really appreciate more than 8 dials and ability to import (ideally - sync) user's own search engines. But your addon is great for starts, especially the arrow choosing method.

Works well.
It would be much bettre if I could have more search engines like 20 or 30 and could add suffix.
I believe 8 search engines are not enough for most of the users.

Addon is ok.
Yoshimo's review is too harsh. You have to take into account that Mozilla limited the API drastically, so most of this is not possible. It's mostly Mozillas fault, you should be disappointed about them, not the author of this addon.

But I have another suggestion: How about show the favicons only after dragging the text some distance. Then the addon would have a similar behavior than Super Drag, another wonderful addon destroyed by Mozilla pyromaniacs.
