Instead of clicking on "OK" and then selecting "New" each time for adding one more attribute to an ENTITY, We can add one more button as shown in the attached image which commits the Attribute and redirects for addition of one more attribute. This saves considerable amount of time.
As Mohamed say CTRL+N is will reduce clicking, also you can you CTRL+Enter to save changes, TAB to stroll down thro pop-up and many more.

Hi Maheswara Reddy,
This is a valuable suggestion. However, you may utilize 'CTRL + N' to create a new attribute instead of repeatedly clicking 'New.' This approach can also help you save time.
