PLEASE LOOK AT IMAGE. i made a similar post, but was referred to PDF output which doesnt have anything about canvas aids for bleeds and margins

This is for print items, and would be like a ruler button in canvas. Its not exported, just an aid to guide Admins and Front end users. I thought it maybe hard to add two internal borders, so if its easier for developtment make it transparent PNG image admins can upload.

(new button added; default colors but i made it red and blue to demonstrate on and off)

NEW: bleed & margins tool enable/upload

Where I can find the "bleed & margins tool enable/upload" buttons?

Will this only work w/ rectangle images? Can we have bleeds on circles or heart for example?

it was said the pdf output would have bleed but i still dont see it. any way to get this to user end panal?
