In v12.0 to v12.2 a new tab was opened in Automic Web Interface (AWI) when an object was opened. This behavior changed in v12.3.
Starting from v12.3 right clicking an object will open the object in the same tab. This is the new design.
The design of AWI was changed to unleash the power that is built into Web Browsers like Chrome, Firefox and Edge.
Release : 12.3
