I was impressed at how simple and intuitive windows resource management was. Of special note are the simple margin and alignment controls found on the dialog editor. The margin controls let you define how close your controls can get to your dialog window borders. It's a simple feature, but it saves time and thought. Better yet are little ruler controls at the sides of the dialog edit window that let you define tab stops for controls.
Any control touching that line becomes glued to it.
Integrated Source Code Control Source control vendors haven't yet fully caught up with visual development tools. The typical source control product either relies on the programmer to identify each and every file to check in or out of the archive, or it makes the simple assumption that every file in the same directory gets archived. Visual development tools create files without a developer ever explicitly requesting it. Consequently, it isn't unusual to lose track of the names and locations of every file. Some compiler vendors approach this problem by choosing one or two source control vendors to support, then building custom dialogs for the operations these vendors require, and integrating these into the development environment.
