One thing that would make debugging malfunctioning code so much easier would be breakpoints. It's incredibly tedious to have to put in message to the world for every little thing just to see if the code is actually getting to where it needs to be. One thing I absolutely LOVE about Visual Studio is the breakpoints.

We could really use the same thing in DM. It would make debugging so much less annoying. Especially when you miss a message and you it gets into the live server. That's just unneeded spam.
