This issue has some features moved over from our 0.2 release #301. They are considered more advanced topics that we'll likely be aiming to have explored or supported for our 0.3 release, which might be around Jun 1 2020.
Enable range mode for dims including slice / max_projection / crop (S/P/C)
Add play button to dimension sliders.
Support units in status update and scaler bar overlays
Does "Support mixed 2D and 3D rendering" have an issue I can follow?
A quick search didn't turn up any, so feel free to create one. @sofroniewn has already done some of the leg-work here by allowing layers to have their own dims (dimensions) model, separate from the global one, so I think this one is less of an implementation and more of a UX challenge.
Layers can also have their own scaling and translation. In terms of e.g. 3D rotations or skew, I don't think we have a great story there yet, but I'm not sure.
If you could provide a small sample dataset, that would help enormously with development.
We're well underway moving towards these goals, and closing out some of the remaining issues from #301. I just wanted to highlight a couple key areas of work that we need to get done before we get close to having API stability, and having a solid foundation for plugins:
