Not at this time, but you can rename individual nandroid backups to something more meaningful. That bug you are referencing is simply aesthetics, and doesn't impact functionality in any way.
Thanks for your quick response. Unfortunately, this doesn't appear to be the case;let me explain. I had several NANDroid backups already in place -- 11 of them, actually. I bricked my first phone before I understood what a NANDroid was, so I became paranoid about keeping backups.
I took a screenshot of the directory listing on my PC so that I could "remember" which ones had been done prior. I then rebooted my phone and proceeded to do another NANDroid backup. The backup did complete -- there were no errors. I then did what I wanted to do (I installed the new ICS theme being developed).
After the theme was installed, I rebooted the phone and took another look at the clockwork backup directory on my SD card. There were no new directories created meaning that NANDroid, apparently, overwrote a previous backup. That's not good. It is possible I did something wrong, but I did nothing different the 12th time than I did for the previous 11 backups.
While I cannot assume to know how difficult this bug would be to fix, my gut feeling is that it isn't too hard and would really add to the functionality of this program to the Optimus Slider. I'd even be willing to take a crack at fixing it myself if source (including a makefile) were made available (perhaps they are; I haven't looked for it). I assume it's written such that a Linux-based make and an appropriate ARM6-aware cross compiler will compile it.
