List all search engines with a command like Vomnibar.activateSearchEngines
Vomnibar.activateTabs or Vomnibar.activateHistory list tabs and history. It would be nice to have a command to list search engines with their keywords. It could be named as Vomnibar.activateSearchEngines.
Why do you want this? All available engines are defined on Vimum C Options page:

Because I have a lot of search engine and can’t always remember their keywords or their domain to call them.
I suggest that you may click Auto Resize button and the read you list of search engines:

Whenever you have used a search engine for several times, you will be able to remember its name easily and quickly. And for those seldom used, you can assign longer but representative names (like website domains' main names), so that if you know a site, you'll know its name.
It’s more of a workaround but ok.
Um, up to now I'm not interested in this. You may keep this issue open to let other users vote it.
