Table order top-down or bottom-up

[natoverse]

The hierarchy is represented bottom-up by displaying the leaf table at the top of the browser list, and walking up the tree as you scroll down the tables (with the tree root being the bottom table). This is the default because starting from a leaf provides a predictable path to the root from a known starting point, whereas starting at the root could require navigation decisions at each level to find a leaf. For our common use cases, we are starting from a known row item that we can trace to a leaf, and showing the leaf table at the top is the finest granularity (smallest community) they are a member of - typically the preferred list to explore first.

That said, top-down is a much more common way of navigating trees so there may be times when it is desirable to represent the tree in a more traditional manner.
