Just going to add that would be nice to close this if possible: https://github.com/napari/napari/issues/5545

> On meeting, we assume that the default behavior should be follow the class. With exception for dask (not possible to fast paint). Could you clarify what you mean for...

> Ok, so, seeing my comment in #6297, I am now leaning towards _not_ assuming that we have zarr, so the button could/should be greyed out with a reason (no...

> Yes, graying out the button solves this problem. ;) I think we differ in the definition of `solves` 😜

Totally forgot about this! From a point of view of painting, we're limited by GL_MAX_TEXTURE_SIZE too for a labels layer. I tried a `zarr.zeros((16_000, 16_000), dtype='u2')` (under my GL limit)...

zarr-python 3.0 For `zarr.zeros((16_000, 16_000), dtype='u2')` I get: ``` In [23]: data.chunks Out[23]: (16000, 16000) ``` With: `data = zarr.zeros((16_000, 16_000), dtype='u2', chunks=(1500, 1500))` painting is much better., but still...

Thanks for opening the issue. I *think* napari already does what you want, but maybe it's not obvious and not documented enough? For single layers, we didn't do this but...

Just to clarify, if you open the Cells 3D sample image you can't save both layers using Save selected or Save all layers? Re: npe2, it looks like something isn't...

Hmm. What data type? Can you use: `viewer.layers[0].data.dtype`? (replace number with index of relevant layer)

Can you clarify? so int64 labels work, sample images work, but `uint32` labels from a plugin don't work? Which plugin? When I make a pair of labels layer using UI...
