     - The existing "Save" button in the floating bar has been split into two distinct actions: "Save and Continue" and "Save and Exit".
     - Tabs are greyed out, and widgets are disabled until the engagement is successfully saved. A helpful tool-tip has been added to inform users that the engagement needs to be saved before accessing certain features.
     - Independent save buttons previously present in tabs, such as "Additional Details", "Settings" have been removed. Now, the floating save bar is universally employed when editing an engagement.
