Required field by Form mode

This module will help you to set a field required only in a specific form mode.
You can keep the field optional for some form modes while required for others.
This module's functionality is tested and supports these entities (node, user, taxonamy_term).

How to use the module:
- After enabling the module, go to any field you need to make it required and keep it not-required from the settings.
- Go to the form mode now, and in the field settings, you will be able to set this field required.

This module is working great with other form mode modules like:
form_mode_manager module.
