'Dm2', and 'Photo Shape'

Dm2

Minimizes windows to floating icons, freeing both task bar and tray bar space. Moreover, DM2 can manipulate windows in various ways: minimize to tray, make them standing always on-top over all other windows, roll to caption, resize, align to screen borders, hide, set the opacity etc. DM2 also helps with Open/Save dialog boxes, by providing user-defined menu with favorites and recent files and folders. Plenty of options.
