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.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,347895055

The current choice has the advantage that it matches `self.dims` and is invariant to the order in which variables were added into the dataset. As for the order of iteration for `Dataset.dims`, at one point early in xarray, I think we had `dims` as either a dict or OrderedDict, but for both of those the iteration order is somewhat arbitrary and can differ for two Dataset objects that otherwise look identical. At least `SortedKeyDict` is ocnsistent.

If we want to change this (which could be OK), I would try to change the iteration order of `self.dims` instead so it remains consistent. Potentially we could make `Dataset.dims` iterate over dimensions in order of their appearance on a variable, data variables first followed by coordinates. This would potentially entail the potential need to iterate over all variables to iterate over dimensions, but I think that would probably be acceptable.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,347895055
