Comment Vertical taskbar + lose the toolbars (Score 1) 1140
1 : put the windows-taskbar (or linux desktop equivilent) on the side(s) of the screen - ideally the left side otherwise it slows down the time taken to hit the scroll bar or window-close buttons with the mouse. You'll have to make it a bit wider than it normally is tall and learn to live with only viewing the 1st few letters of the window titles.
2 : combine as many menus or toolbars together as possible - eg. in Firefox have the menu, back/fwd buttons and URL location all on the same line. Not all windows apps seem to allow you to put toolbar buttons on the same line as the menus, but wherever that feature exists you should use it.
3 : Remove all the other toolbars / excess status-bars - use the menus or learn keyboard shortcuts for your favourite applications (using the keyboard shortcuts is vastly more productive than hunting the toolbar buttons)
4 : Modify the window theme to make the fonts and icons for menus, window-titles, scroll-bars and min/max/close buttons as small as possible that you can still read them / click on them.
5 : (this one I have more problems with) - try using auto-hiding menus / panes / taskbar (notably in visual-studio which has many many panes of useful info). This one I'm not so keen on because it slows me down considerably, having to first move the mouse to make a pane show, then move the mouse to select the item of interest. Similarly you can try to use full-screen mode in apps that have it available and you don't need to view multiple apps concurrently.
