A feature to do per-world spam/flood protection would be nice. Basically, do what the Speed Walking 'Filler' does, but for ALL commands. Make MUSHclient detect if you've sent too many of the exact same command (the amount to trigger spamming could be set by the user), and have it send the 'Filler' text automatically (also this text should be set by the user).
zMud has had this feature for a long time, and it's one many like.
