There is currently no way to control the default Sorting behavior, which I think is somewhat limiting. I almost always would like to have my folders and collections sorted by Filename. Insttead, newly created folders and collections are almost always sorted by Capture Time, which is far less useful to me. I think it would be very helpful to have a setting for Default Sorting for New Folders and Collections, with options being the twelve option found in the Sort dropbown.
I often put a lot of time into organizing and sorting photos in the order I want to present them, and then renaming chronologically so they are named in order. When moving phots around between folders and collections, the sorting often get broken when the default sort by Capture Time is applied, and it is annoying to have to go through every folder or scene and have to set each to sort by filename.
In leui of a new Sorting mode setting, I think sorting by Filename by default would be more helpful for most people than Capture Time, since most cameras name photos sequentially anyway, so the result would be the same in most cases while importing new photos. But it would allow more flexibility to users who wish to rename files in the order they want.
