Filters in Planners
From Planfix
Search filters are available in the Planner. To use a filter, click the filter icon. A window will open where you can enter a word or part of a word. This will filter out all objects in the planner that do not contain this word or part of a word in their name:
Using a planner is the same with or without a filter — you can, for example, find a task or contact and drag it to a different list.
To remove a filter, you need to click on the cross (if the field with the text of the filter is open) or on the green filter icon.
