I tend to run my resolution much higher than most people and have plenty of real-estate. I would love to be able to stretch the dialog boxes so I don’t have to horizontally scroll list box dialogs such as the beer style dialog.
You could always move to Managed Code and make use of Winforms. I know they have a simple property you can set to the dialogs you create to allow them to be resized quite easily.
The next version of the framework that is being worked on ( been using beta1) will have a bunch of other fun and cool controls for the toolbars, menus, etc.
The pain, of course, is having to redevelop a lot of the infrastructure code that makes BeerSmith so easy to use. Unfortunately I'm going to have that pain no matter which option I choose.
