In version 2.528 you moved the links from the left sidebar to the Menu Items. Please provide an option to add the links to the left side bar on the Main and Jobs pages. When you make changes like this you should always provide an option to allow teams to keep the original format or move them under the menu item.. I like to have the links on the left side bar so that they are always readily available to my users. It would really be nice if you make the links in the left sidebar collapsible just in case there are many links.

The Main page on the new GUI looks cheap and less appealing than before. Greatly disappointed with the new GUI changes. The Jenkins logo looks really cheap also, It seems like Jenkins is downgrading everything and going in the opposite direction instead of making improvements. Jenkins did the same thing with the weather icons several years ago. The icons were downgraded.
