Hi,

If the main reason is to avoid accidently changing parameter values on a production system, there might be some extra obstacles that can be configured besides a different UI theme:

• In the Cube settings, it can be configured to always display a confirmation box (this is by default activated). See this help section option "Never ask for confirmation after setting parameter value" . I would definitely advise to have the confirmation active on a production setup.
• Another possibility could be to remove the write rights from your user. This can be done by e.g. under the rights General->Elements->Data Display->View write parameters, or per element under the view security to disable the "Write" checkbox. If a value needs to be set then either enable the write rights again (but don't forget to disable it afterwards), or login with a different user (such as the Administrator) that has the write rights
