Very little not to love

I've developed dashboards for sales and marketing using Tableau, as well as supervised others building dashboards. I generally find it very easy to use. The online tutorials are extremely helpful and have gotten me past most issues I've faced. There is functionality that is still lacking that I would like to see. For example, it would be helpful if you could do multi-step aggregation, which isn't available now. This causes the need to do some aggregations outside of Tableau and create another data source.
