It would be nice to improve look and feel a bit as in attached "screenshot", so that:

• a case when content is used in more than one page is done by showing "many usages" in url column, which can be collapsed
• whole row is clickable and it opens edit page in new tab
• a proper hover effect on hovering over url should be added so it's clear that this is different action (page view rather than edit view). It should also open in new tab
• we drop hamburger menu icon in usages list as both actions (view and edit) are already covered by clicks (either on row or on url)

if Edit > label in each row looks redundant/annoying we can show it only on mouse hover
