I think that, for a new version, it would be good if:
1 - we had a way to preset the frequency via numeric pad (I don't know how to do it in this version of the program).
2 - we had all the special symbols in the CW.
a - (AR), (VA), (KN), (AS),
b - the accented letters (', ^,~) and C with cedil
It may not be important for english, but it is for other languages.
I would also suggest that the text we put on the 'Station Information' field accepts the special characters like '-', '_', '/', for example. They are useful for portable operation (as mine now) and for information of e-mail addresses that may have those characters.
