I polished up an old project from 2008, CellRename: a file-rename utility with a spreadsheet-like UI. Take a look at my brand new Github to download (supported on Windows and Linux).

features include:

I tested on Win XP, Win7, Win8, Ubuntu Linux, Fedora Linux, Mageia Linux, and Mint Linux. Credit pyinstaller as a great Python stand-alone tool.

This is only the beginning; there are many more half hour hacks to be unfurled.
