What we really need more than anyting I can think of is a more automatic spell checker/corrector. there is no reason why i shold have to correct the same misspelling time and time again in every email becasue misspeliongs tend to re-occur most frequently.
For example in MS word and most email programs, if I misspell “the” as “teh” i can have the program automatically correct it so that each tim ei type “teh” it will be corrected to “the”.
This is just indispensible in my opinion.
