[Layer Masks]

I may be missing something, but in Photoshop you can "apply" a layer mask to the image. (i.e. the mask disappears and becomes merged with the layer.) The nearest in Affinity seems to be to go up to the Layer tab and "Rasterise ..." the layer. (I'm not sure why there are dots, as no dialogue box comes up.) Wouldn't it be easier to have the option (along with all the other options) when you right click on the thumbnail?

[Nik Collection support?]

I use the Nik plugins a lot and I do find it odd that they work in most other photo software perfectly well (including PhotoPlus), but they are all almost unusable in Affinity. Maybe it's something to do with my set up, but many of the options fail to even show up, let alone work properly. This is a real "deal breaker" for me. I do hope that this problem can be "sorted" and that the release version will fully support all the Nik Collection. (and, hopefully, most other Photoshop compatible plugins!)
