You can report the bug at Issues tab. But make sure:
- It's not already reported
- You are reporting at correct client/server.
- You have explained it clearly
- Explain the feature clearly
- Also implement it at other clients (if you can)
- Do NOT make something that clearly creates an security issue
- If you took the idea from an issue, or if there was one, you should mention it
- Do NOT make something that clearly creates an security issue (Yeah, again.)
- Explain it clearly
- It will NOT be accepted
