How to ... on Vomnibar

1. How to always search queries case-insensitively?

• When mapping Vomnibar commands, add an option of icase in "Custom key mappings" on Vimium C Options.
• For example, map o Vomnibar.activate icase.

2. I don't want people to see my history in the bar when recording my screen. Or I don't want to search in tabs.

• Add engines: Enum: to do so. For example, map o Vomnibar.activate engines=29
• engines should be composed flags of bookmark = 1, history = 2, tab = 4, search = 8, domain = 16
