This was my first thought, as well. I use Dash several times a day. It has been indispensable for me. There are a few main things that will probably keep me on Dash, for the time being. In no particular order: 1. Global shortcut - Being able to quickly show-search-hide from anywhere is extremely useful for me. I can quickly refresh myself on the syntax of an uncommon function. The faster I can do that, the less likely I am to break my flow. 2. Support for random/obscure projects - On top of community-added docs, Dash lets you point it at any random GitHub project and it will pull down the README. This has come in handy plenty of times for me when using small tools and components. Sure, it's not as nice as full documentation, but it's nice having that README searchable in the same place and offline (see reason #1). 3. Docsets - Dash lets you define groups of frameworks (etc.) and name them. You can even specify which version of a framework to use in the docset. This allows me to tailor my results to a particular stack, depending on which project I'm currently working on. EDIT: I should read :)
