[Feature Request] Option for a custom bang prefix

[Axhyy]

Thank you for creating this project!

A feature I've been searching for in projects similar to this one is having the option to change the bang prefix.

For example, instead of "!yt example" if the prefix was set to ";" it would be typed as ";yt example"

Just seconding this request. CustomBangSearch does exactly what I want it to, but I would much prefer to use ? or / as the "bang" because it's more ergonomic to type than !.
