@Sven, I was wondering can you adjust the "mask" feature, so that it would highlight what it is about to clear (just to make sure that's what I want to remove)?
Also, another thing I noticed (and maybe im using it wrong) but when I use the mask feature it doesn't seem to work very well. Lets say I want to clear out all the domains/emails with the word "cars". When I actually perform:
No matter which variation I try ES only deletes some but not all.
And now that I take a closer look at it, does the mask feature check the URL's or is it only emails?
