One of the annoying things about Windows is when you need to browse inside a sub-folder of the one that you're currently in, but without losing your place or selection of the current one.
With AlomWare Toolbox, just hold down the left mouse button for half a second on any folder to peek inside it from a pop-up list that appears. Double-click any item in the list to open it, or press Esc or click away to close it.
Note: There's a setting in AlomWare Toolbox to show the peeked view as either a list or as thumbnails.
