I've got venture funds to build a cloud IDE, what would you want to see?

How will it be different from Github CodeSpaces, CodeAnywhere, and other ones out there?

CodeSpaces works really really well

* Be able to work offline

* Good vim emulation, use neovim as a backend if possible

* Make it easy to configure and extend

* Low input latency

the ability to develop iOS apps in Swift and test them without buying a mac or an iPhone
