(Click to enlarge screenshot) Kicad multiedit lets you open a KiCAD schematic and edit values of many components in a single operation, instead of one component at a time. At the time of writing, it seemd that KiCAD doesn't have this functionality, and it can be very tedious to edit components one after each other, in many places, in many sheets.

The program runs on Win32 and Linux (32 and 64 bits).
KiCAD is available here: http://kicad-pcb.org
