When someone works with some crappy piece of work software, they don't think "I wish it had XYZ features", they think "I wish I had a better job"
I mean this seriously. I really don't like any of the solutions that I've worked with (although Looker does check a lot of the boxes, it also has some big blind spots), and I want to create my own reporting suite in the future.
Besides, after seeing many options over the years, I feel that I could make some substantial improvements.
