You should post this in Feature Suggestions, I was thinking
the same thing a while back that if the /timers command is
used that it should only display the timers for the current
connection and dynamic/global timers. Also, switches could
be added to specify which timers to display...
/timers would display global timers and local timers for the current connection
/timers -g would display only global timers
/timers -l would display only local timers for the current connection
/timers -gl would display global timers and local timers for the current connection
...just a thought.

Oh and a switch used when creating a timer to force the timer
name to be specified when stopping, so it can't be stopped using
/timers off but I think this one has already been suggested.

Nevermind, I posted it.
