Would be better if... Rated 3 out of 5 stars
Would be nice to have two types of "removal", which correlate to CSS properties:
Hide - removes element and collapses the space
Make Invisible - removes element but retains space
I'm looking for something that would work with Pixel Perfect (graphics overlay) to make only certain elements invisible. Web Developer extension hides or makes invisible images on an all-or-nothing basis. Something with focused control would be special.
