In the task list, we can manage the tasks and select the tasks to run.
Task three structures
Project: The project is a large category, and there are multiple directories under the project.
Directory: A directory is a small category that can have multiple tasks under a directory.
New: When the file does not exist, create a new file and generate new content based on the template.
Merge: File already exists, According to the template merge the specified part, other parts remain unchanged.
Overlay: The file already exists. Overlay all the contents again.For example, here is a task structure for the Web project
Right click menu or right button to see the following actions.

The task has 3 following states, these states are automatically updated according to changes in the environment. For example, the template has syntax errors, and the file directory cannot be found.
If there is a syntax error in the template, or other error or warn, the task status will change
Task status is automatically updated, but sometimes there is delay, you can use refresh.
