Display Rules in forms are very powerful, however they limited by the IF condition being limited to fields on the form.

If it were possible to include a Text Formula field within a Form or allow the Display Rules to reference a Text Formula within the IF conditions, it would open a lot of possibilities.

Use Case Example:   
OBJECT for House  
House: House 1  
Pets Allowed?: YES  
-  
House: House 2  
Pets Allowed?: YES  
-  
OBJECT for Tenant  
Name: John Smith  
-  
OBJECT for House Tenant  
House:   
Name:   
Type of Pet:  
-  
If a form is adding a record to the House Tenant object  
- Type of Pet field for selection would be displayed if House 1 is selected  
- Type of Pet field for selection would not be displayed if House 2 is selected
