I think it would be useful if the word filter had an option to switch on/off a certain filtered word as case sensitive.
example: I want to filter the word f*** but not the word F*cK, so I turn off the checkbox "Turn on case sensitivity for this word."
This is especially good with abbreviations.
Example: I am going to ny (---> Plus! would now change this to New York, but I dont want it to. I want it to change it to New York when i type NY)
etc.
