WinRoll

WinRoll is a tiny and straightforward program that makes it possible to enable the window of any open application roll into its title bar, minimize to the system tray area, stay on top or behind all the other windows. Plus, you can change the transparency level. It targets hardcore computer users who want full control over their system.
The installation procedure is rapid and does not require special attention from the user. At initialization it creates an icon in the system tray area, where you can toggle the utility's status status as well as set up the necessary configuration adjustments.
Instructions on how to use the mouse buttons on the frames are displayed in the About panel, accessible through the tray icon's context menu.
When it comes to program settings, you can set WinRoll to run at system startup automatically, hide its icon and restart to show it again, and to ignore the middle mouse button. Furthermore, it is possible to adjust the transparency level of the frames, as well as select an option to minimize them to the tray, between icon and menu.
The application is extremely low on the system resources, using a minimal quantity of CPU and RAM. Unfortunately, it has not been updated for a very long time, and we have come across some stability issues on Windows 7, as the tool caused an application to crash while we were tinkering with its frame. Other than that, WinRoll is very easy to deal with, thanks to its overall simplicity.
