Roadmap

During the first half of 2018, the team is focusing on the following features:

• Debugging

  A visual debugger leveraging the Debug Server Protocol defined by the VS Code team.

• Workbench Improvements

  Theia's workbench shell will be improved, such that the user can drag and drop widgets from the side bar to the main area and vice-versa.

• Search

  Theia already can search files by name (CMD + P). In early 2018 a full text search shall be developed and added.

• More Git Support

  In addition to the already present commit staging view, the team will add a git history and git diff view to better visualize the different states of git repositories.

• Navigator Improvements

  The file navigator shall support decorations, which are to be used by the git and the problems view extensions. It will allow to signal on a file whether there are git changes resp. diagnostics.

• Better Markdown Support

  The Markdown support shall be improved to allow better preview that syncs scrolling. Also rendering plug-ins based on markdown-it shall be supported and tools like linters and dead link checkers shall be integrated.

• Robustness and Improved UX We will further work on simplifying Theia and its UI / UX, improve the performance and keep working on bug reports that are rolling in.

• More

  Any contributors might want to work on additional things. At least this happened in 2017 and is likely to increase with a growing community. :)
