I would love to see the ability to search for a report either with a search or filter button (similar to the filter that we can use in Custom Forms).
Right now I have built my own filter which I call "Name Contains', but I have to go in and modify the filter every time I am searching for a report.
As a system admin - searching for existing reports in the list that generates would be useful so that I can reuse reports versus creating a new report that may already be out there and available.
