Adjustable zoom behaviour in Affinity Photo?

[Thor, the Norseman]

Could we get some options to adjust zoom behaviour?

 

• Option to always (initially and/or consistently) display documents at the nearest rational zoom level (e.g. 1:3, 1:2, 1:1, 2:1, 3:1, ...)
• Option to always initially display documents at 1:1 (with option for "Small images only" and "All images")
• Option to always use nearest-neighbour scaling for rational zoom levels greater than 1

 

I would also prefer it if the zoom level could be made to never change unless the user requests it.
