7) Optimization for menu position is the wrong optimization It seems that for most applications today menus are only used to access more advanced functionality (the hidden 80%). Where the majority of use with an application is via toolbars and the scrollbar. Toolbars are across the window, and scrollbars are on the right. Though, it's unclear to me how many people use scrollwheels. These screenshots tracking mouse position[1] while using Photoshop seem to point to that for me. But, of course, Photoshop has more palettes which are less common in standard programs. The program is available here[2] but I haven't tried it. It might be interesting to grab results with users doing things like webbrowsing.

Tabs are an example. Subwindows can also be an example. Perhaps we should move the tab close location as well? 9) The majority of people are right handed This would make it more natural for those folks to do things on the right side. This isn't done with menus as menus are aligned left-to-right like text. But for items that have no relation to text it would make sense to put them on the right side to match the majority of user's natural tendencies. I bought a Kindle DX[3], and I was worried about the controls being only on the right, but I've found it surprisingly natural (I'm right handed).
