 # Features
 *(The following is not a complete list of features but a work in progress to build a comprehensive feature list.)*
 
+## Data Browser
+
+### Filters
+
+▶️ *Core > Browser > Filter*
+
+The filter dialog allows to add relational filter conditions based on other classes that have a pointer to the current class.
+
+For example, users in the `_User` class may have:
+
+- purchases in a `Purchase` class with a `_User` pointer field
+- transactions in a `Payment` class with a `_User` pointer field
+
+A relational filter allows you filter all users who:
+
+- purchased a specific item (in `Purchase` class)
+- payed with a specific payment method (in `Payment` class)
+
+To apply such a filter, simply go to the `_User` class and add the two required filter conditions with the `Purchase` and `Payment` classes.
+
 ## Browse as User
