Updating Quick Access Panel

I'm uncertain if this can be achieved but decided to inquire. In the access panel (shown in the attached screenshot), I am interested in repositioning the following items to the top instead of Home and Gallery:

- This PC

- OS (C:)

- Data (D:)

I attempted to drag them but they do not remain in the desired position.

Furthermore, in Explorer, when sorting by date, the folders are displayed before the files. Is there a way to have the files appear above the folders when sorting by dates?

Thank you for your assistance.
