Having something that would detect anything modified in the .jar would be aburden for many, including myself. I use single player only mods, such as the elevator mod. This would most likley be picked up by a detection plugin and boot me from the server. I 100% understand why you wouldnt want game changing mods in multiplayer, I dont want them either. But, I dont think Notch will be fixing the chat anytime soon, its definetly not on his priority list. The only multiplayer mods I have ever used is Zans minimap and enhanced chat. It can be extremly useful to copy and paste spmething into chat and have a cursor to go back and fix a typo without having to delete everything before it. I agree with Static, having a dark monitor is no exuse. I have a pretty dark monitor and I am able to explore caves with no torches at all. I dont think using a mod like a minimap or enhanced chat will give you an advantage over anyone else, as these mods are available to anyone. Notch and the Mojang team cant please over 2 million people with everything they want. That is why people mod.
