The experience using Flow on Opera desktop gets worse, the more items you've added.
The primary usefulness of Flow is to quickly share sites between devices. It's not a bookmark keep.
I know it's probably advised to clear the Flow on regular basis, but you'll often reach a certain amount of sites (which you don't want to clear at that moment) when the issue arises:
You need to scroll all the way to the bottom, util you reach the latest added site in Flow!
My feature request is simple: Add Ascending/Descending chronological order to the Flow list. Or arguably, consider switching to Descending (newest topmost) because that's in my opinion the best UX for the purpose of Flow.
