For me, two things:
I don't like the way I have to scroll sheets using the two arrows, rather than a scrollbar. I like the right-click option however that provides a sheet navigation dialog, but I miss the old way of scrolling.
I don't like the behaviour of CONTROL+TAB. If I have three or more books open then it seems to toggle only between two books. It didn't behave this way in pre 2016 versions, if I recall correctly. Maybe I just need to flip a switch somewhere to change the behaviour?
I will also echo what Joe mentioned. I recently had to describe the difference between two balances - one being derived in Excel and the other in TM1. The difference was purely resultant of precision! It's also not fun trying to explain how the precision difference has come about!
On the plus side - I recall similar topics over the many years that I have been frequenting forums. Suffice to say that many things that we used to gripe about are no longer issues, such as repeating key values in Pivot Tables and a range of formulas. In particular, I find TEXTJOIN tremendously helpful. Excel continues to grow in leaps and bounds!
Oh isn't that ever the truth. If you're copying data from somewhere and you need to
---- Uh oh! You said [Ctrl-Tab] not the same as [Alt-Tab] which from some change that
maybe wasn't to Excel but maybe windows. When I want to [Alt-Tab] from Excel through
various tabs that I have open I have to [Alt-Tab][Alt-Tab] twice to get out of Excel and
into the rest of the tabs that I have open. It ruins your rhythm it does.
Getting rid of blank data that appears as zeroes in your graph is another annoying chore
when you deleted the no data place holder -9999 or whatever the originator of the data
decided to use.
Recently I find that the equation displayed on your graph i.e., y = 0.123x²- 456x + 789,
doesn't have a function, ƒx, for those three terms. Maybe on the next version (-:
And those G**D*** little yellow flags that cover up your data to tell you something about
some formula some where and you can't turn 'em off.
But the biggest annoyance is the Date Function. Down load some data off the net and
there in the middle a date instead of your number shows up. That has caused some
serious errors for me.
Not an Excel issue but those key board toggles [CapsLock], [NumLock], [ScrollLock]
and [Insert] can really screw things up. And the [Home] key doesn't go to [A1]. Oh
that is an Excel issue.
