Allow admins to control settings and defaults for other users
Unless I'm very much mistaken, the only way for HubSpot administrators / partners to configure things like sales email signatures / meeting links / chat availability or edit profiles of other sales users is by logging in to each individual's account independently.
This is a really cumbersome process, first having to obtain login details for X number of users, and then log in to each account and configure each setting accordingly.
It would be great if this could all be managed from an administrator / partner account. For example, create a bulk-standard thirty minute meeting link that with availability between 9am and 5:30pm, and make that available to every sales user in X team. Or, design one email signature and roll that out to every user (or a specific team), using personalisation tokens to update the custom details.
