In Affinity Photo, if you hold alt+click and drag a layer, it should create a copy of the layer. In Photoshop it's a really quick way of creating copies of layers.

I couldn't agree more. It's really slow to have to move the cursor up to the top bar every time you want to change the radius or hardness of brushes.

In Affinity Photo, it would be nice to have numerical input for Curves control points, allowing more precise values.

I am keyboard phobic and have great difficulty with shortcuts, so pop up right click context menus are a very useful shortcut device indeed. for me. Now that is a very personal problem but I am sure there are plenty of others who find well implemented context clicking a very focused way of getting to just what you need in a given context. I find that this is rather inconsistently applied in the Layers Palette. There are things one does very rarely included there and things one does frequently that are missing.
 
I think the following need adding to this menu when the appropriate layer(s) are selected.
 
Merge Down for mask and adjustment layers. You have to go to the main layers menu to find it. 
 
Merge Selected for multiple layers. Once again you have to go to the main mayer menu to find it.
 
Invert layer (very useful for mask layers). Only available from main menu.
 
Lock Children. It shouldn’t really be necessary to have to select the Pick tool and then select this in it’s property bar. To my mind it properly belongs here in the Layers Palette context menu as well.

I think it would better for the workflow to have the context toolbar as dialog boxes with the specific tool options for each tool on right mouse click, like in photoshop. Maybe also a keyboard shortcut to resize brushes, pencil etc with mousewheel :)

I could see this feature being very useful, especially since some game engines (E.g. Unreal Development Kit) require textures in power of two sets.

Holding Ctrl+Scrolling back and forth one "notch" at a time makes zoom level to slightly decrease every time.
 
Another thing i'd like to see is if Ctrl-Scrolling could snap to pixel-perfect resolutions. Now, it very often zooms to uneven numbers like 97%, making everything slightly blurry or other artifacts.
