It intended to help you working with window in much more efficient way.

It comes with 5 essential features, which are available for quick access from a new menu attached to every windows title bar. Menu options only appear on mouseover, and the container can be moved across the title bar.

Most features are familiar and explain themselves. but some are innovative and need an explanation -

Shrink Window:
Too many minimized windows in the taskbar? have a big mess in the taskbar?
you can minimize windows in a way that they will not shown on the
taskbar. they will become small squares that stay on top. each square
is minimized window. Now you have new space to minimize your windows, not only the taskbar but also the screen itself.

Set Window Dark:
Sometimes you may want to stop see this bright light that comming from your screen while you reading or writing something. You may want to see in dark mode, as I doing just now while writing these lines.You can eliminate all the bright white color by one click on the 'SET DARK' button. it works on every win32 program. not including Windows 10 only apps.

Click Through:
It even gets better now! You can do set window transparency and on top. BUT you still lose something - you have less working area on you editing software.. You may need from time to time to move the window that you set on top. Not while you use this feature + Set Window Opacity feature. If you turn on the Opacity + TOP + Click Through, then now you also not loosing beneficial screen-working-area on the editing software.

Opacity Pro:
Make everything transparent except text and images in the window!. (Using a smart image processing algorithm)
