Type Stats and Filter. Pops a menu of all file types contained in the current folder or search results, ordered by count. Click any of the types to filter the list by this type. Killer feature.

The command is located in menu View | Tab.

There is a toolbar button available with the same name and functionality. You can modify the sort order of the popup menu via right-clicking the button. There are two options, Sort by Count and Sort by Extension. Credits for the icon go to http://www.fatcow.com/free-icons.

For example, you have a folder full of various file types, but for now you are just interested in MP3:

Click the Type Stats and Filter button and select "*.mp3" from the dropdown. (Click to see the full screenshot)

Violà, now you have a clean MP3-only list. (Click to zoom)

Apart from serving as a quick filter, the dropdown shows you which file types are contained in the list and the counts of each type. Works as well in branch view and search results.

Straight-forward to use, powerful, and clean.

Recent File Operations. Pops a menu by which you can apply recent file operations (Copy and Move) to the currently selected files, using the same operation and target path as recently.

The command is located in menu Edit, and Alt+F7 is assigned to it as default keyboard shortcut.

There is a toolbar button available with the same name and functionality. Credits for the icon go to http://www.doublejdesign.co.uk.

For example, you have a folder full of pictures, and often you need a picture from this folder to be copied to a particular folder on another drive (D:\Temp). Well, you don't even have to remember the drive or the name of the folder. The Recent File Operations menu does it for you, even if the last copy was long ago:

Click the Recent File Operations button to quickly copy any files to the same target as last time. (Click to see the full screenshot)

The menu also offers other operations that were previously done from this location, and, in the second section, operations that were previously done from elsewhere.

Tip: Hold CTRL to go to the selected target path (instead of repeating the file operation).
