I finally got a chance to turn on the breakpoint functionality. I added this a long time ago before the language parser was developed, so the hooks have been dangling there for quite some time.
I can safely say this is one of my favorite features of any debugger. Simply being able to throw out a breakpoint during execution is SOOO helpful during the debugging process. EUO has some nice debugging features, but sometimes getting to the bit of code you want to start debugging can be a task. In EUO, you can randomly hit the pause button and then single step to the desired location. But with ScriptUO, you can just add a breakpoint to your breakpoint list, and if the code tries to execute past this point, the script will pause automatically. From there you can single step, examine memory, etc.
