Link directly to Excel tab
Each tab in excel document should have unique url, so that sharing a link pointing to a specific tab is possible.
This is a good idea. I use several workbooks, where first worksheet summs-up all the information from other worksheets and since not always I want to show my exact calculations, I need to send it as a PDF file.

Our team uses a shared workbook for recording time on a personal tab, with a separate tab for combining that information. We also work simultaneously within the workbook during the workday. Currently, the workbook always opens to a particular team member's tab (which may change after a check-out/check-in cycle), confusing other team members and sometimes leading to entries on the wrong tab. It also opens in view-only mode, which is rarely used. Ideally, we should be able to launch to our own tab, and in "Edit in Excel Online" mode.
