"Smart Eraser"  functionality in Spectacle

Hello, I would like to request the addition of a "Smart Eraser" to Spectacle. 

Directly inspired by the Smart Eraser in Windows exclusive tool ShareX, which is functionality I have sorely been missing. 

Functionality wise, it would function identically to the existing "Rectangle" tool, however this rectangle would have no Stroke, no Shadow, and the Fill color would be sampled at the cursor position when the user starts drawing the rectangle.

Not being familiar with ShareX, can you go into a bit mor

…a bit more detail about what this would do? I'm having trouble understanding the existing description you wrote, sorry.

Hello, of course I'd be happy to elaborate. The utility of a smart eraser is to more subtly obfuscate or remove things from a screenshot, effectively identical to just covering it up with a rectangle. The main difference being that instead of the user having to go through the process of manually picking out the color to fit the image, the RGBA values would be sampled at the moment the user begins holding the left mouse button, after which the user is free to shape the rectangle however they see fit.

Please do not hesitate to inquire further if you require me to elaborate further.
Thank you!

Hi again Nate. You are welcome. However seeing you, or perhaps someone else, have modified the title, I feel obligated to point out that the rectangle in question should have no border/outline/stroke. Thank you!
