If you are interested only in certain topics, you can use the Tracks filter to filter out your sessions.
Step 1: Open tracks filter
If your event supports tracks filtering, you should see the filter button in the upper right corner of the Program screen.
Step 2: Filter your sessions
By default, all tracks are selected, to deselect the ones you’re not interested in, click on them. Deselected tracks will turn transparent (buttons without fill color).
Step 3: Check the sessions related to your selected topics
Now that you filtered out topics you're not interested in, you can see the sessions that match your taste highlighted. Sessions of the hidden tracks will be semi-transparent.
Note: You can open both selected and un-selected sessions, the only thing that’s changed is their design.
