"Release Mask" or "Flatten Clip Path" Right click option for clipping masks.
When one creates a clipping mask using two or more objects, it should be a simple right click option to "apply the mask" and flatten all related objects into a new vector. Currently you can do this by going to layers and selecting the "Clipping Path" layer of choice and then using the "Crop" Pathfinder function to achieve this, however, this method is extremely non-obvious. I don't propose removing the pathfinder function as a way to apply clipping masks, but simply to add a more obvious way to do so.
That is because there is no such a thing as Apply Clipping Mask :)
You can clip art that is far away from being able to be cropped: meshes, linked images, live brushes, text... Crop is a destructive thing. Crop removes all live strokes form the objects within the mask and messes with order of objects. It’s NOT a Flatten Clip Path and is no meant to do it, it’s a basic boolean operation that occasionally works as it can substitute Apply Clipping Path absent command.
Unfortunately, there is no one, I wish we had though.
But there are script that try to substitute it, like Super Magic Eraser: https://mai-tools.com/super-magic-eraser
