Copilot Feedback - Power User Experience Improvements

Hi Bart, this is a thoughtful list, and I think the "power user mode" idea is the strongest way to frame it.

Copilot has to work for new users, but people using it daily for architecture, Power Platform, SQL, governance, and troubleshooting need a denser workspace with fewer interruptions. Suggested prompts, large spacing, and accidental `/` or `@` triggers can get in the way when you are already deep in a technical flow.

I would submit this through in-product feedback as grouped themes: compact view, configurable shortcuts, conversation search/pinning, and memory transparency. Those are easier for a product team to route than one very broad request. The copy/code-block improvements are especially important for technical users because small formatting mistakes can waste real time.
