I know that there is Zen Tao, which feels too detailed and has a lot of redundancy, which makes it difficult for some people to understand the use of the system.
has also used teambition, but the feeling is mainly relatively simple, it feels like it is used for simple task assignment.
JIRA+Confluence, there is no in-depth experience, but mainly to crack the configuration, which is more troublesome.

hopes to solve is:
teams assign task time nodes, which are friendly in reading, that is, it is convenient to check their own tasks and other people"s collaborative tasks, care about what they want to do, what is left undone, and notify them of what is done.

there are specific controls on the schedule, such as the requirements need to be changed, the changes need to be re-reviewed, but continue to be re-modified.
what is the stage of the product, what is the task at the current stage, what is the progress, how is the BUG, requirements, and functional development?
