I have to agree, especially for powers.
The potential things that could be accomplished with having all the powers in a spreadsheet are vast. Things like comparing relative strengths, deciding (via visual comparison on a table) when powers are too strong or too weak compared to others of that level, etc.
I have actually started such a spreadsheet for powers, but I quickly decided it wasn't worth the effort. I can post it if you're interested and maybe the community as a whole could fill it in over time.
