Please make presets without all the green stuff (see screenshot), and with a black background, since RGB is additive color mixing, which starts on black rather than on white. See how your After Effects fellows deal with video :-)

I personally never need rulers and a center mark, since we exactly know where objects are, and where the center is by using Smart Guides and Transform.

(But I am curious who likes all the green clutter you have to clear when starting a document based on these presets.)
