This might be a niche idea but I suspect other people face this problem. I'm in year 7 at my institution and we've used Canvas LMS for 6 of them. As a result, I have 6 years worth of student data. I often have students for as many as 4 courses during their time at my institution, and I both a) encourage the talented ones to go on to graduate school and b) encourage them to take time between undergrad and grad if they do so. Today I find myself in what is a totally normal situation for me--writing a recommendation letter for a student I taught....2 years ago? 3 years ago? Not sure!...in three courses. 

I would love to be able to fire a search for a student's name that would seek through my Canvas courses  name and pull up all this students' work so that I can write with specific examples about the things they did in my courses ages ago. At a bare minimum, it would be nice to just see "Oh right this student was in course 123 on Fall 2018 and course 456 in Spring 2019."
