Too temperamental
Awkward and not consistent. I got through doing a copy/paste 5 or 6 times and then it just quit working. The first time I got back on track by restarting the program. The second time, nothing I could think of fixed the problem. Lots of wasted time. Formula entry is very awkward as well, in my opinion, as is fill option (2-step for range of multiple rows and columns).
