Is your feature request related to a problem? Please describe.
When I am developing an app I use Realm Studio to add properties to my classes, I might misspell the property name or want to delete it again after testing it. I might open the Realm as a local file from my disk or via ROS.

Describe the solution you'd like
As an administrator I would like to modify and delete properties on a class of a Realm that I've opened in the Realm browser.

Describe alternatives you've considered
Deleting the Realm and re-creating it from scratch.

Additional context
None
