When Auto-Matching Loudness, Give a Visual Indication that it is Working

[jport1290]

When using the essential sound panel, the auto-match loudness feature is nice to have...but it gives no indication that it is working.

A progress bar, or even just a wheel beside the button that rotates to show that it is doing its thing, would be a nice reassurance that the reason not all the clips are showing that their loudness has been matched is not because I missed them when selecting, but because it is currently working on it. Sometimes it finishes in a few seconds, but in larger projects, it can take several minutes.
