I think it would be extremely helpful to have tasks/approvals included in the global search results. I am honestly baffled that these were not included already. These are core features of each request, incident, change... they should be searchable in case someone needs to find one.
On top of this, we should be able to add our custom modules to the global search. I know that the custom modules can be a bit advanced, but at least give us the ability to search for ids. even if there is a limit of 2 or something, it would really increase smax functionality and encourage more custom modules which I know microfocus is always looking for.
