heres one thatll come in handy

  var %a = $dname, %b = $devent, %c = $did
  if (%b == sclick) {
    if (%c == 2) {

and the dialogs $iif for incase you try to open the dialog once its already open

Allow Editer: dialog $iif($dialog(Allows),-v,-m) Allows Allows

u also dont need to check if $1 == !addtext so much

on *:TEXT:*:#: {
  if (!addtext == $strip($1)) && ($strip($2)) {
    var %a = write $2 $3- | .notice $nick $2.txt has been added
    if (%aol == 1) && ($nick isaop $chan) { %a }
    elseif (%ool == 2) && (%nick isop $chan) { %a }
    elseif (%hol == 3) && ($nick ishop $chan) { %a }
    elseif (%evl == 4) { %a }
    elseif (%offl == 5) { .notice $nick Addtext is off }
  }
  elseif (!view == $strip($1)) && ($strip($2)) { play $chan $2 }
  else {  }
}
