With R80++ we've got an ability to implement Shared Layers. It is an interesting feature that allows us to have common security parameters across multiple policies.
Having used it for a while, I've bumped into this scenario:
Client has multiple, geographically distributed gateways.
We have implemented common APPC/URLF layer across individual policies governing their corresponding location.
Occasionally, one of the locations requests modification to the APPC/URLF which business approves and it is getting implemented.
Policy is published and installed on that location only.
Now we have an untold number of pending changes for the rest of the infrastructure and those will not take effect until all the policies are installed.
My problem is that there are no clear indicators in the rest of the policies that the changes are pending installation.
Perhaps having a Layer specific indicator of installation status will be helpful.
