Please add the option to duplicate brushes.
The desktop-version has got it. As the iPad-version does not memorize edited brush settings, the only way for effective workflow is creating a set of brushes, that meet the personal requirements. As without brush-duplication-option every self-created brush needs to be created from scratch, the quickest way at the moment is creating brushes from duplicates in the desktop-version, importing them into the iPad version. Works - but is very inconvenient.
