This is a minor one, but annoying. It happens in more places than just this, but this is where I notice it the most.
When creating service desk items, I select the category first, then create items in that category. When I save the item, it returns me to the main screen, and I have to select the category again. It would be nice if it would return me to the last screen I was one, being the category screen.
Perhaps could be addressed by providing a breadcrumb, like in the CMDB
