An option to create derived relations based on the value of another relation of the same object
Describe the solution you’d like
Derived relations are basically formulas from notion. A simple derived relation editor with built-in functions to perform operations on the other relations assigned to the object. This enables the relations to be more dynamic and brings more flexibility to anytype. To improve on it, an option to add custom functions can also be provided. The syntax need not be complex and custom functions can be restricted to be made only using the built-in functions. It can also be possibly made to provide functions through plugins as well. A simple example for a derived relation is a Days left till deadline relation for a task type which computes the difference between the current date and the end date and displays it.
This request goes in hand with another request i made:
Since derived relations are specific to an objects state and is based on other relations which may or may not be available in other type of objects, a derived relation should be coupled with a specific object type and should not be listed in the add relation list in the create task view
