Those are EXCELLENT news :) It is good to know that it is not a limitation. It simply wasn't added in yet. Actually I found out that Excel 2003 had the same problem with cores/threads (in addition to the limit of lines). Looking forward to test 4.1.0 rc1 next month !

No, this is a single sheet. Actually I was considering saving as ODF to test, but I can see that won't help at all.

Great! Looking forward to a brand new Calc! Thank you for your extensive answer! I'm sure this is interesting and exciting for all Calc users!
