Layered Image question : Hiding a specific layer?

[ChroniclerOfLegends]

I just started playing around with the new layered image system recently introduced, and I love it so far.

I am however having difficulty with one aspect.

This may be a dumb question, but how do you hide a specific layer/group/attribute?

The exact problem I am having is that I have effects that are not shown by default:
anger mark, blushes, other standard 'anime extreme expression' effects.
I can easily show them by calling the attribute:

show character blush.

but... how do I get rid of it afterwards?
Once I show it, I am not sure how to make it go away...

I mean, I could save a blank image with nothing in it and make it a 'clear' attribute I guess. But I feel like there is probably already a way that exists that I am missing.

Sorry to respond to my own topic, but I found the answer and wanted to share if it helped anyone else.

You don't need to make a blank image, just add a blank attribute to anything you want to be able to completely hide like so:

attribute noeffect default:
null

Or more simply, just remove the attribute.

show character blush

Will show the character with the blush

show character -blush

Will remove the blush again.
