I was kind of expecting to get the order shown when looking at the dims property but i understand your point and it makes sense.

Two things are still bothering me though: - ds['foo'].to_dataframe() and ds[['foo']].to_dataframe() might have different results - if we want to have a specific order we have to apply reorder_levels and sort_index which can be quite expensive.

For the first point I don't think anything should be done, it's a special case and even if it could be easily tested it might be ugly. For the second point I would not change anything to the way the order is defined now, it's consistent and easily predictable. Instead I would add an additional optional parameter to to_dataframe() (the one from _to_dataframe(ordered_dims)) to allow the user to get the order he wants.
