-******************************************************************************
-Please everyone working on KSpread:
-
-Get yourself a copy of Excel 97 or 2000 and create
-a really big sheet, and I mean really big and insert Graphs and
-lots of dependencies and regressions etc. use external add-ins if you have any
-and real time links. Make links between sheets and then see how
-well Excel behaves.
-
-1. UNDERSTAND that putting a spread->recalc() or spread->recalc(true) in
-your code is an abosolute NO-NO! Complex spreadsheets with possible
-heavy mathematical calculations via dll/so add-ins as well as real
-time feeds will not be managable if you do not painstakingly check
-wether spread->getAutoCalc() is true.
-
-
-2. Learn to understand that without the
-following short cut actions you are lost ( try to scroll
-down a list of 10,000 obersvations ...not using CTRL Down
-for example)
-
-CTRL Up/Down/Left/Right
-CTRL Shift Up/Down/Left/Right
-CTRL Home/End
-CTRL Shift Home/End
-Shift F9 versus F9
-
-Let's try to get them working well in Kspread as well. I tried my
-hand at it but wasn't able to get them to be efficient.
-
-3. Familiarize yourself with the concept of array formulas and why they
-are necessary (area protection, partial argument evaluation) Who would
-be willing to implement them? This will be an absolute must if we
-want to make progress on the mathematical/financial/statistical
-function side of things. I would be willing to implement a miriad
-of these functions but I believe doing that without having array
-formulae first will be a big mistake.
-
-(In case you wonder why I feel so strongly about these things:
-I am a professional user of Excel. I eat, sleap and work with Excel
-on my trading desk on Wall-Street.)
