DM2
DM2 provides several Windows enhancements that may help in every-day work. One of the nicest and most popular features of DM2 is minimizing windows to floating icons® (unique feature!) 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 programs settings options will satisfy most of requirements.
And that is not all! DM2 also supports custom plugins, which further enhances the program and that usually covers some more specific functionalities. So, from this aspect, one may think of DM2 as a small, but robust manager for all kind of plugins. Find what you need, plug it in, and use it:)
