I'd like to see Alteryx allow a second install of your license on a second, personal machine. Tableau allows this and IMO is why there is such a robust online / blog community around that product.
For those of us that work at mid-size to large organizations, there are often strict rules governing internal data and use of cloud-based data sources. If I discover some new trick I'd like the share with my fellow Alteryx analysts outside of my company, I have no clear way to do that the same way I can with Tableau where I can do it at home not using my company's data.
Being able to learn new features and test things out on commonly available public data (ever notice that Superstore data set everyone who gets Tableau has?) would accelerate what we're able to do with the community site here and the larger analytics blogging community.
