I love this but some room for improvement....
1) The recognition result can sometimes be obscured by the initial writing. can we shift them apart a little.
2) Editing dialogue when tapping is too small to use on the N97 (even with stylus is challenging)
3) Auto scrolling would be nice feature
4) Ability to add terms to middle of expressions through some form of insert stroke
5) vertical scrolling as well
6) ability to paste history into working area to continue editing
