"Everything" is great software.
My one problems is that when the list of found files comes up, and one double-clicks on it to open that file, the Everything window remains in the foreground as the active window, hiding the opened file.
It must then be manually minimized to see the opened file.
I suggest that "Everything" minimize automatically in favor of the opened file.
