1. The news is too worrying. The working group often has a lot of useless news, for example: a lot of likes, I am the same, 1 and so on. Then when you want to view some useful content, it will be very difficult. It would be nice if there was a thoughtful function.
2. File system. The same file is saved repeatedly, taking up a lot of space. Suggestions can refer to the practice of git. There is only one copy of the same document.
