Being a font nerd, it would be so great, and incredibly useful if all the Affinity apps for iPad were able to seamlessly import free Google Fonts. The free app Fontasy is able to do this already with various apps, including LumaFusion and ProCreate. Sadly Affinity apps are not on the list for saving fonts to. Please allow this functionality in AffinityPhoto and AffinityDesigner (and by extension the AffinityPublisher for iPad which will be available one day.)
Thank you and keep the awesome flowing!
