Hi @lord-kyron This PR contains a large number of changes in the overlapping parts of the code. Therefore, to speed up the work, they were merged into one commit. First major implementation - added ability to manage l2fomains The second significant change is the refactoring of Unit tests and bringing them back to life.

There are also a number of smaller changes that affect bugs and fixes discovered after the restoration of Unit tests

This issue fixed here too.
