Please add the text search box to the filters in the message templates just like you have in the course enrollments filters section.
When trying to find or edit a message template, the UI forces you to scroll through the pages or the long list to find the item you are looking for. Maybe it's just me, but I tend to search for terms like "enrollment" and see the results that populate to remember which item I need. Is it "online course enrollment" or "ILC enrollment," etc. The current setup doesn't allow me to do that in the message templates filters, but the same functionality exists on other reports throughout the system. Please add the text field to all reports where able.
