select text, drag to search with customized engines is the most frequently used option. But it can not pop up search engine list by default, you have to drag it to the icon. not good.This review is for a previous version of the add-on (0.11.1-signed.1-signed).
Thanks for your feedback.
However, the 'default' behavior should be as simple as possible. That means it shouldn't need any extra actions other than a simple drag'n'drop.
If you needs other search engine than the default engine, you can always drop it on the right place.
Hope that can help.
