In 14.3 version, we have a custom built portlet which shows data for Request for Estimates object (sub-object of project object). In this portlet,there is a link on Estimate ID which opens up Request for Estimate page on a new window and when user click on Save & Return or Return, it redirects to portlet list layout.
Now we have upgraded to 15.3 and here while clicking on Save & Return or Return redirects back to Project properties page and after again clicking on Return, it redirects to portlet list page.
So, a user has to click the Return button 2 times as opposed to 1 time in 14.3
We just wanted to check if there is design changes implemented in 15.3
