I've ofter observed that during implementations where there are multiple environments it becomes difficult to identify which environment a form belongs to especially when there are multiple forms open form different environments (Live, Test, Prod, Training etc). I made a very simple tweak which highlights which environment a form belongs to. Very similar to the AX 2008 Workflow band. This was successfully tested in AX 3.0, AX 4.0 and AX 2009. Its really very simple and effective. See screenshot below.
The XPO is attached below. This XPO is for AX 2009 SP1 and the SysSetupFormRun class was modified.
