Refresh/Commit always is performed on all databse objects. Even if I just change 1 object, I have to wait until all is refresehd, unselect all changes that I don't want (from other objects), commit and then wait again until everything is refreshed.

By default the refresh/update/commit should only be used for the select object(s) in the object explorer. You can offer configuration or buttons to "refresh all" or a checkbox "perform for all objects".

The automatic refresh eats unnecessary time during development.
