As a response to your questions, please see how we’re thinking about open source here: https://github.com/warpdotdev/Warp/discussions/400
As a side note, we are open sourcing our extension points as we go.
The community has already been contributing new themes (https://github.com/warpdotdev/themes). And we’ve just opened a repository for the community to contribute common useful commands. See: https://github.com/warpdotdev/workflows
