Author of Datastar here. Most people don't need pro and it seems like putting it on the front page is actually marketing it instead of people finding it as the need the features. Not only should most people not use the features we actively push against it. The only thing that's really super valuable is the inspector which is a Dev tool
As someone who actually happily bought Pro, I completely agree with this. Inspector is great, and worth the (nominal) cost of Pro. I might use a couple other of the pro functions. I'm very much looking forward to Stellar CSS and Rocket Web component framework getting released - they'll DEFINITELY make pro worthwhile, and given that they are completely new, there should be no qualms about it being purely pro.
