For example, I [can't?] stand Sec, Csc, Sech, and Csch > and would rather see Sec^-1, etc. I'm with you on this one: always hated Sec and Csc (and never understood the backward naming of these functions -- why isn't Sec = 1/Sin and Csc = 1/Cos?) So, I'd like the various Simplifiy and XxxToYyy functions in Mathematica to always give precedence to Sin and Cos by default, and avoid using Sec and Csc whenever possible, even if this produces some "1 overs" in the output expression. But I suspect trying to implement this at this point would require more complexity than it would be worth.
