Worksheets and workbooks

I'd like to view two worksheets at once

Can I make my window smaller

Can I name the worksheets something other than SHEET1

How can I hide certain data in my workbook

I want to increase the space between each row of data

Can I change the order of my worksheets in my workbook

What are worksheet panes

I'm having a hard time pulling up a workbook

I'd like to have a different default font for all my new workbooks
