I love the idea of being able to switch the search engines by mouse wheel, but the function of switching the search engine by mouse wheel destroys Linux Copy-&-Paste. Please make an option to disable it.
Always wanted to have an add-on like this! But it doesn't work too well together with the WheelClear add-on that I'm already using to EMPTY any search field with a mouse scroll. Would be great if this here could be made (perhaps optionally) to work only if the pointer hovers over the search engine SYMBOL, so if the pointer is over the white field only the WheelClear will work.
