Commands show names only, not menu paths

[ctrueden]

In the ImageJ search bar, you can see the menu path of each command:

But in napari-imagej, only the command name is visible:

So it becomes difficult to know which Image... command it's going to run. (You can click Source, but it's an extra step that opens a web browser.) It would be better for napari-imagej to embed the menu paths, in a similar fashion to what the ImageJ search bar does.

So it's not too bad to get the menu path, but it is difficult to color them differently, like we do in ImageJ. I think the most performant way to do it is something like this, but that's really in-depth.
