Of course, I'd still like to see a native /AEcho.
Yes, a "echo global" feature could save some mechanical looping, even though I don't have problems with that. As pointed out, it is scriptable.
But, instead of some new command, one or two new "echo -something" switch(es) would be sufficient and allow to keep using the other established echo switches.
e.g. a hyptothetical:
-o > echo "global" (echo to all windows besides 1) status window, which can be addressed by adding -s, and 2) custom windows (don't touch them :P)
And, if wanted, also a hypothetical:
-x > echo to all channels
-p > echo to all queries
EDIT: Ah, and there is that scon thing, but to echo "realy" global, the command could be prefixed easily with "/scon -a", or should this be the next switch? We're running short of letters
