Get comments from reblogs.This extension allows you to view comments added by rebloggers on any post in your dashboard. Just click on the new "reblog comments" text next to "notes" to see them.
Note: It's still a bit glitchy from time to time. If something looks messed up, please try refreshing the page. I haven't been able to replicate the positioning and animations of the notes pop-up completely, so look forward to future updates :D
