I have written a fairly small application (10 small classes). I have tried to follow best practices in terms of software design but I have a feeling it can be improved.

It is acceptable for me to post the entire application's code in codereview-se to be reviewed, or is that too broad.

I don't really have any specific questions but rather "please review my code and offer improvement suggestions". I probably could extrapolate individual questions but I think it would be best to see everything in context of the entire application. I would of course explain what the application does and a high level overview of its design also.

So I just want to check here first before posting such a question
