Hello Peter, Thanks for the info. I'm still trying to see if I can do what I want with the stock flow layout.
FWIW, it appears that the behavior of the flow layout class is to center items when there is one section. This appears to be a summary of the behavior: Collection has one section: • Items on each line are centered on the line, including multiple items per line. Collection has multiple sections: • If one item in the section, center on the line. • Multiple items per section, flow from left-to-right, including across lines. I wish the multiple section case was consistent flowing left-to-right.
