I liked the way Apple did it in their Numbers clone of Excel - you can have multiple grids on a single page. It makes it a lot easier to have related data on the same page without fiddling with the row/column sizes to suite multiple types of data.
* Freeze header rows & columns.
* Naming header rows & columns.
* Graphs that don't overlap the sheet.
Things that I find Excel does better than Numbers from a data perspective:
* Data validation
* Large tables
* Formula Error checking
But anyway...
* You can freeze header rows and columns in Excel.
* You can place charts outside the sheet with data.
* I'm not even 100% sure you can't name columns, but let's say you can't.
So, Excel has 2 out of its 3 "missing features". Just saying.
Recently I’ve just been using numbers because it’s there on the odd occasions I need to access an xslx file and, while everything is a little different, it’s just better.
If you have Excel running, open the Activity Monitor and find the app in the list. Then look at "Kind" column, you will see "Intel" listed. So that's why Office365 are sluggish on it.
Thanks for letting me know!
Safari? Lightest-weight usably-well-supported browser around, by a long shot. Preview? Outstanding for a bunch of reasons, including that using it is the only time I've been happy to receive PDF files. Pages, Numbers, Keynote? More than enough for everything I do, stable, and I like that I can leave them open in the background for weeks and they're light enough that I forget they're there. Notes? Not having a built-in export function is annoying and I wish I could use markdown formatting, but it's so good at everything else that those haven't been enough for me to switch to something else. Hell, I even like the calculator better than most others.
