[Galaxy S I9000 Android Development] supercurio:
Sure.

The logging feature has been enhanced to give more useful informations about what the lagfix does, still in a readable way.

Also,logs are managed and old infos are deleted automatically.

The voodoo_history_log.txt in sdcard/Voodoo/logs will allow you to see quickly the list of what Voodoo lagfix did before.

There is also a limit to the maximum filesize for it: no worry about deleting it manually.
