Greetings.
Currently (r305), if you go to the edit page of a connector function, click on its name, change the name and description and click Save, the changes are actually not saved. You also have to click the Save Changes button.
I’ve often found myself leaving the edit page of the function only to realize the renaming I had just done and saved wasn’t applied. I personally don’t find that intuitive at all.
I think the name and description should be saved persistently when the Save button is clicked.
