一些建议：
1.标记指定工程为：喜欢，以便收藏这个工程。
2.根据用户开启工程频度来判定星级。星级范围：0~5.
3.创建支持折叠和展开的分组。
4.工程列表子项支持拖曳，便于指定分组。
some advises:
- Mark the designated project as: Like, in order to collect this project.
- Judging the star rating based on the frequency with which the user opens the project. Star range: 0 ~ 5.
- Create groups that support folding and unfolding.
- The project list sub-item supports drag and drop, which is convenient for specifying grouping.
