That's a good question @kmuehlbauer, and the distinction probably needs to be clearer in the docs in general.

> reduce over all given dimensions?

By this do you mean find the minimum as if the array were first (partially or totally) flattened along the given dims somehow? I'm not sure we provide that kind of behaviour anywhere in the current API.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,594594646

+1 for overloading `argmin` (and later `idxmin`). IMO we should never have one function for a 1D operation and one for an N-D operation if we can avoid it, everything should be N-dimensional.

I also really like how neat this resultant property is
```python
da.isel(da.argmin(list_of_dim)) == da.min(list_of_dim)
```
we could even use a [hypothesis](https://github.com/HypothesisWorks/hypothesis) test to check it...

> I think returning a dict of indices would be much more useful, but it does change existing behaviour (more useful because you can then do da.isel(da.argmin())).

Although it's breaking and would require a deprecation cycle, I think this is what we should aim for.

Yes let's take the time to make that clearer for users - this will be a commonly-used function.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,594594646
