You can filter your activities according to three criteria:
- Date: Use the date filter on the left to only show activities in a specific period.

- Project: Select projects from the project list to only show activities belonging to that project.
There are two special projects: The "Unassigned" project (which contains
all activities not belonging to any other project) and the Blacklist.

- Duration: Use the duration slider on the bottom right of the window to hide short-term activities.
