Time Tree plugin has two main commands:

1. Compute hierarchical (aggregating) elapsed time from a root note descending to the leaves notes (no links to other notes);
2. Update metadata of the current note and its ascendent notes.

The first command can be time-consuming, hence the existence of the second command that only needs to update the necessary metadata as it goes (can be set to trigger automatically when the time tracker ends).
