I've been using Affinity apps for only a couple weeks. It is possible this requests already exist, if so I have not found them.
Currently, if I understand the iPad app correctly, the Home screen provides file name without extension, pixel dimensions, color space, and bits. That's all. The option to see the extension would be very helpful, especially when working between the iPad and Desktop version. On the Desktop the extension is visible.
There does not seem to be a way to save to , edit in, or copy to other applications. Nor does there seem to be a way to save to the Photos app.
