Now that you have an idea where to find various filters, let's actually create one. To add a filter simply find the filter you wish to add, select it, and then click Add to Filter in the upper right corner. Say we want to create a simple filter for hands that we won. We can go to Hand Details and click Win/Loss.
This brings up more details about win/loss, where we can toggle Player Won Hand to ON. Once you've done this, click Add to Filter.
The next window shows you what the current filter is. In this case, it is just Player Won Hand. From this window we can cancel, add more filters, save as a quick filter, clear all filters, and more. If we wanted to just run our filter with Player Won Hand, just click Save & Apply Filters in the upper right corner.
This will apply your filter and your data will reflect that. To see which filters are currently applied, look in the Currently Active section along the left. In this example, the only filter is the Player Won Hand filter we just applied.
