Currently, an icon only lets the user know if a file or directory is currently being shared.

It would be awesome to enhance the icon a bit (e.g. with a little clock in the corner of the icon) if the user set an expiry date for the folder. This way I do not have to click on the icon and then on the settings icon in the dialogue to check if it is set.

The same can be done for password protection: Adding a little padlock quickly lets the user know that a password has been set for the shared document/directory.

If a clock and a padlock (or both at the same time) are too small, maybe they can be displayed additionally next to the share icon. Clicking on one of those new icons directly opens the respective dialog for editing the expiry date / password.
