Always in Sight is a feature that has been developed to solve an issue that you may find inconvenient on certain circumstances when working with ClickLess.

The problem occurs when you move the mouse to go to another window. The former goes to the background, sometimes getting hidden behind the latter. In that case you would have to resize the foreground window to access the background's.

When you click Options...Always in Sight (to make it checked) and perform the same operation, the window goes to the background but it repositions itself in a way it can be accessed easily without having to resize the foreground window(s) to find it.

Of course, if you don't like Always in Sight, you can disable this feature just by clicking Options...Always in Sight (It becomes unchecked). Even with this function disabled you can make all hidden windows accessible again by pressing CTRL + F6.
