First thanks for making sheets but here are a few features to make it better.

Save the view, currently if i shut off guidelines, i have to do that each time i access the sheet, that same has to be don't with shared links. please include a way to save if they are on or off in the file

Open to the last page worked on - for sheets with multiple worksheets withing the document, it would be nice to open to were i left off and not tab 1

Printing - set print area, if you scall to fit to a page, it should add more of the sheet to the page and not scale like an image.

Option to set the page oration within sheets and print area for a sheet
