Hello,
I am a CheckBook user (very satisfied one!). I am also a Mori (notebook) user.

I see from CheckBook Message board there are many requests for different features. This is common with all software.... We are never happy! LOL.
I am not sure how you decide to develope your software and if feature requests play a big part in that process. Jesse, the developer of Mori has a very efficent way of doing this. On his site he allows users to suggest future features and these are voted on. Those at the top of the stack have more chance of being developed and should meet with customer satisfaction because they voted for them. You can see this in practice here:

Hope this is useful.
