I don't think a textview should take of filtering, it should just  
display a string. The controller should take care of the filtering,  
which would be more an MVC approach.

That's indeed a more MVC approach, so I will look into that.

BTW, I think you forgot to include the Color_Extension and  
String_Extension files. The latter I guess contains the  
filterDNABases method?
