Perhaps make /showmirc behave more like /window

current /window:
Code:
/window [-abBcCdeEfg[N]hikl[N]mnoprRsvwxz] [-tN,..,N] [+bdeflLmnstx] <@name> [x y [w h]] [/command] [popup.txt] [font [size]] [iconfile [N]]


current /showmirc:
Code:
/showmirc -mnrstxopl


... or be able to send a the mIRC main window as a parameter like this:
Code:
/window $window(-2) [x y [w h]]
