Open Windows Manager can make you manage all the open windows more conviently. At first, Open Windows Manager collects all the open windows into a popup menu, and it also puts a small float and transparent window(32*32 pixels) on the top of the screen.

When you let the mouse move over the float window, the popup menu which contains all the open windows will pop up to you immediately. So you can switch to any window as quick as a flash.

When you make the left mouse button click on the float window, the popup menu can pop up immediately, too. Also you can define a hotkey to pop up the popup menu (it can be defined in the dialog name 'Options'). Of course, you can drag the float window to any place of the screen(put the mouse on it and make the right mouse button down, then move the mouse), it means that you can switch the windows at any place.

Finally, you can minimize all the windows by using the right mouse button double clicking on the float window.
