On first run, there is a significant time spent downloading models.
In fact, it seems all models are downloaded, not just the selected one—it took ~5 min on my machine, just now.
While there are progress indicators in the terminal (I launched napari from terminal), there is no visible indicator in napari that something is happening.
Ideally, napari would show in the activity monitor that it is working.
Also, if possible, only the selected model would be downloaded.
Thus the user would know what's up—that it's not broken—and the process would be quicker, since only 1 model would be downloaded.
