I have a six page list of bugs, problems, complaints, critiques, and -- yes -- compliments.
How can I send you an e-mail listing these for you to read at your convenience? (Who knows, you may even find something funny in my missive.)
Michel, why not use this site and post the more relevant ones, see if other users agree, if it is already implemented, get feedback from others, solutions to your problems, etc.
That way, it might be useful to others as well!
And also, please state the software that you talk about...
