[Affinità panel]

Hi. I opened a new blank file on Affinity and then I closed it (or so I thought). Subsequentely I opened a raw photo on Affinity but the panel is small,all I can see is the photo and the  I don't get the develop button, all I can use the exposure saturation etc but then I cannoni apply the changes I have made because there is no apply button. Can you help me?

[Affinity unsuable]

I downloaded The trial Afinity version on my i Mac. It runs in El Capitan  and it has a memory of 8 GB, 4 unused. The hardware memory is of 499,25 GB, of which 215,79 unsused. Affinity doesn't recognized mt camera when connected to the computer in order to download photos (I shoot in raw) and it is impossible to download more than one photo at a time even when the camera memory card is slotted in the computer.Also, once I have managed to download one photo, it is very very slow. In other words, it is unusable. Pity!
