## Description
Users expect the Web IDE to behave the same with or without a workspace. Being able to add a runtime environment without leaving the Web IDE would improve the UX. If this isn't possible then we can at least improve the empty state of the terminal.
## Proposal
The empty state of the Web IDE terminal refers to remote development documentation and provides a CTA that allows users to configure a remote environment. However, we could improve this by providing more guidance and streamlining launching a workspace without leaving the Web IDE.
## Notes
From [UX Scorecard](https://gitlab.com/gitlab-org/gitlab-design/-/issues/2531): "Maybe I could launch from the Web IDE?"
