I have always regretted locking the cabinets. I would be interested in what you think about CabWriter leaving them unlocked. As a developer I am always needing to unlock them to try something, and find it a pain in the butt to do. So I could be convinced to leave them unlocked and let the user select all of them and lock them when they wish to.
I am less inclined to add more tools to the toolbar. But I would like to hear others thoughts on it too. Maybe we should send a questionnaire to the users to get more opinions.
