When there are 400+ people online there is way too much garbage in the text buffer. I was just tweaking my firewall and thought how firewall-like rules could help me get the information I want to see while filtering out the garbage. AH could use a robust squelch system with a configuration file similar to a firewall config...
# AHsquelch.conf - example
squelch 1
squelch 2
squelch 6
listensquad ammo on 6 # allow kill messages from squad only
squelch rewolf
listensquad hblair on 2,3 # listen to assassins on channel 2 and 3
listensquad fatty on any # listen to fdb on any channel
squelchsquad shane # would only effect channel 3 based on previous rules
Basically an aceshigh dot command batch file with a few added commands and features. I could at any time .listen all and then .filter to re-enable my filter set. There would be no limit to the number of players you could squelch and the filter would be loaded when starting AH if filtering was enabled.
