about this plugin
Pidgin Windows Position Manager is a plugin for Pidgin that allows the user to globally set the size and position of conversation and other windows that are part of Pidgin.
As of version 2.1.0 (?) Pidgin now saves some window sizes and positions. However if you still want total control over all the Pidgin windows, or if you want the ability to globally show or hide the formatting bar within conversation windows, then you may still want this plugin.
Also, this is unofficial, but within the prefs.xml file for Pidgin, in the extpos settings area, you can enable a couple of keyboard shortcuts. Instructions are on the F.A.Q.
