Show Only Red/Yellow Edits on the Map

[Nakaner]

Could you please add a checkbox which hides all tiles which only contain "green" changesets, i.e. if the checkbox is not checked (default), WhoDidIt should be behave as usual and, if the box is checked, WhoDidIt should only show doubtfull edits?

I am hunting a vandalist (I do not want to say who and where to make hunting easier) who changes accounts and I want to know if he changes is region of acitivity. At the moment I have a couple of RSS feeds on his region of acitivity.

Thank you.
