I use the conditional disable structure in my projects to turn debug options on and off.
At the moment before every build I have to go into the project properties and make sure that DEBUG variable is set to FALSE and after the build I have to change it back.
You can get around this by automating you build but an option in the build specifications would simplify this.
It would make life much more convenient if there were a list of the available (non-system) conditional disable symbols in the application builder dialog where the appropriate variables for the build could be set. This would also allow for a simple duplication of a build spec to have one with DEBUG=TRUE, and one with DEBUG=FALSE.
