Yeah, this was very unintuitive for me!
Relatedly, it would be really nice to have a data loader that recognizes RGB images (pngs, jpegs). Glue already recognizes AVM (hooray!), but then there's a lot of extra setup dragging in 3 different layers and coloring them appropriately.
Often a biology data cube will be a true color image -- so three channels and the default way the user wants to view it is with each channel scaled between 0 and 255 and color-coded to pure red, pure green, pure blue. Currently this is a lot of clicking in the UI.
One option would be a plug-in that just sets this up correctly for a data cube (i.e. the user selects which channels are RGB and the plug-in creates a correctly configured image viewer). This is less discoverable than having something directly in the Image Viewer controls... though assuming we put the plug-in into the core package we could also provide a button that runs the plug-in from within the Layer Options or Viewer Options UI.
To make an RGB image from a single dataset with multiple components, users need to add the dataset to an image viewer multiple times. We should detect this kind of case and show a warning/note in that case next to the layer list as this is not intuitive.
