Once again, thank you hotkolbas for your input.

@ MohammadAG - Thank you for the pointer, I am using diskusage and so if that is what illumination can do...then i am definitely taking the next step. I so much want to contribute with an app for the N900.

@ gerbick - What is crazy, is that this is one of those instances, where you find something totally by accident..looking for one thing (basic excel formulae training/tutorials) and then end up with something totally different - ilumination.
