My team and I work on a custom Outlook add-in. It is frustrating for users and us developers to have to pin the add-in panel several times a day.
It would be great to have a feature that pins the add-in automatically, providing the window size is large enough. The existing breakpoints for desktop could likely be used. Ability to manually close the add-in would still be required.
Or at very least give, MS could give developers the ability to manually code this feature into their add-ins.
