Instantly narrow down the notecards you are viewing with Filters. This menu can be found in the top left beside the Noteboard title, or you can open it using "Cmd / Ctrl" + "F".

Using Filters
When you open the Filters for the first time you will notice 'Not Invisible' is on, this is the case as Invisible cards are hidden from your view by default.
Enable / disable
Click on the name of a filter to enable / disable it.
Include / Exclude
Click on the icon of the filter to include / exclude it. e.g. if you wanted to hide all the cards that are tagged with '#uninteresting', click the hashtag. i.e. this is applying a NOT operator to the filter item.
AND / OR Operators
Click on the "Using AND operator" dialog in the bottom left of the menu to switch between using the AND and OR operator combining together the different items.
Reset to Default
By default the "Not Invisible" item is on, along with "Not Archived" (if viewing within a parent card). This happens as usually you don't want to see Invisible or Archived cards. To disable these filters just click on the names of these filter items (as mentioned above).
Types of Filters
You can filter by a variety of different things...
General
The following filters are always present in the list.
Not Invisible (on by default) - cards marked as 'invisible'
Mine - cards you have authored
Liked - cards you have liked

Keywords
Type any phrase and your first option will be to create this as a keyword filter – represented with a little search loop icon. This filter looks for an exact match within a card title and body and is case insensitive. You can also combine multiple keyword filters together.
Authors
If friends have shared cards with you, they will appear in the authors section represented with an '@' icon.
Tags
All the tags that you've used on your cards you can filter by. You can also instantly filter by a tag by clicking on it while a card is in 'Display' mode.
Colors
Filter by the 8 different colors that a card can have. Useful if you are using a color coding system.
