Hi there! As you're new to this repo, please make sure you've used an appropriate issue template and searched for duplicates (it helps us focus on actual development!). We'd also like to suggest that you read our contribution guidelines and our code of conduct. Thanks a bunch for opening your first issue! 🙏
Do you mean the categories disappeared? I somehow couldn't understand what this issue is about...
@JQiue it's not clear what your issue is from the lack of text description and the single screenshot. The only issue I see with that view is what AW suggests: categorizing your data (e.g. development, study, etc.).
Please fill in the other sections "to reproduce," "expected behavior,"... etc.
