I’m very glad to see this. Now that Apple (through High Sierra) has possibly bought another year or two for Aperture, it will hopefully give you guys more time to develop a DAM that matches the standard of the other Affinity apps.
BTW: there is an awesome feature called Light Table in Aperture that NO OTHER software seems to have (at least none that I can find) – please, please build an Affinity version of it into your DAM.
