Side navigation would have these items: Overview, Backend, Frontend, QA, DevOps
The images that current exist on Features would go into Overview page.
The content withing Technical Features would go into the Backend page. There would be columns .NET and Java. Current statuses (DONE, TODO) apply to .NET. For Java everything in TODO at the moment.
For Frontend, the technologies are: Angular, React, Vue
