Is it possible to change the default page size (5,10,20) in list layouts?
the ask is to load 20 records by default, and for the user to have the option to load either 5,20 or 50 records.
It is by design to limit the options to be
[half of default page size, default size, double default size]
So for your use cases the options will be [10, 20, 40] if default is 20.
However the capability of changing the default page size is not exposed yet. Please log a ticket through your account manager, or a NexJ Project manager.
