I feel like a broken record. The OP uses windows. The comment I replied to insists Windows is garbage and the OP should jump ship, because there's no hope for Windows managing windows. It's ludicrous to suggest Linux to OP, when he simply wants to manage his PuTTY windows differently (Re: his WM technically already manages the windows [grouping], but it's not what he wants); it is made more ludicrous by the fact that there exist tiling window managers for Windows -- see my other comments to SIBLINGS of your's. Not that a tiling manager is going to be of ANY help in OP's case; I really doubt the auto-scaling and tiling of his windows is what is making him struggle with dozens of PuTTY instances.
