In my personal opinion, the current way how PSPad handles windows, side-panels etc. is quite okay. Well, there are some things which could be better – for example, I would like to be able to change the order of tabs in the tabs side-panel by means of drag & drop –, but the LMD demo doesn't seem to support that either. Also I noticed some strange behavior in the LMD demo when when trying to change the order of tabs in the tabs top-panel.
Frankly, I would prefer you to concentrate on the new editor engine. There is one feature that I really, really miss in PSPad: Smart highlighting (like in Notepad++) -- <http://forum.pspad.com/read.php?2,68739,68743> PSPad freeware editor http://www.pspad.com
