For issue #7 you mentioned above, we have just released a new version(2.7.4) on 10/12, and would you mind testing on our latest version? I believe the issue is fixed. Let me know if you still encounter the problem.
For students' network connection issues, could you please provide me more details? like what network and devices they are connecting, also in what user scenario? Additionally, we optimized the mechanism of reconnections on the latest version as well. It might solve their issues.
For issue #8, we totally understand the need and have put this into our product roadmap.
