I would love to see an /updateui. Most complaints about mIRC being single threaded seem to be related to UI freezes etc.

Whilst the script would definitely be slower, that could be mitigated by updating the UI after every N iterations, like this:

Code:
var %i = 1, %str = $str(a,4000)
while ($left(%str,%i)) {
  echo -a $v1
  inc %i
  if (%i // 10) updateui
}


Would definitely be handy to have smile
