Describe the bug

Can not find opacity action/condition for Button object. If there are some technical limitations/reasons for this, then why tweening opacity works correct?

Sorry, if this is known and explained ages ago, could not find anything.

Steps to reproduce

1. Create Button object.
2. Search for action that lets set opacity for this object. Or condition to check current opacity level.
