I like how easy it makes browsing documentation, because you can search by keyword or class/method to quickly find what your looking for! Also being able to see code snippets from within another application was really helpful when learning Swift 3 in Xcode 8+. So far so good but there isn't any way of adding custom keywords that aren't listed under "Search". The ability to add new APIs would be great too - maybe with some sort of free trial? It could also use more features such as comparing two versions side-by-side which we've used before (but not anymore!). Would love if they added this feature again at least until their price goes down even further. We're using dash primarily just about every day throughout our entire team now, so having something else out there has been useful since most people are already familiar with Apple's docs anyways though still want other choices available sometimes.
