As I mentioned before, I’m working on the next update. I’ll be including the multiple memories and a bug fix for 0^0 power. It currently reports 1 which is only correct in certain contexts. I’ll be changing it to Error (indeterminate), which is a more accurate overall answer.
Lastly, I have a whole slew of new, very nice themes coming…which I think you’ll like. Many of the old themes are either going away or have been slightly (or fully) re-imagined. Let me know if you really, really, really like one of the current themes and I’ll consider keeping it.
Stay tuned for more details!
