Bang is great, but not as convenient as it could be.
I have to shift-1 to make a bang, which isn't the end of the world, but it is cumbersome.
I suggest adding the 'tilde character as a synonym for the !bang symbol. eg: `gi (google images), etc
The bang can continue to work, just add the tilde as an alternative.
And since others (and other keyboards) may prefer other characters, a setting to customize whatever symbol you want to use for synonyms of !
