Pin and Category

[StudentWeis]

Is your feature request related to a problem?

I'm always frustrated when important topics or frequently accessed categories get buried in long lists as new content is added.

Describe the solution you'd want

• A "pin" button/option for both topics and categories
• Pinned items always appear at the top, regardless of sorting criteria
• Visual indicators (e.g., a pin icon 📌) to distinguish pinned items from regular ones
• Ability to pin multiple items with custom ordering among pinned items
• Easy unpin functionality
• Pinned status persists across sessions
