I've been searching for this for a while, as members who creating a thread with a lot of pictures, let's say 100+, they will have to scrolling up and down to insert the attached pictures, which is a pain. I've tried to make the attachment editor position fixed so it will help a little, now I am thinking it would be nice to make it as overlay effects and draggable. After being searching over the internet for many days, I thought this could be a good option: Dialog | jQuery UI Draggable | jQuery UI These two links give good examples so I was trying to modify the code myself, I managed to find the template "thread_create" "PAGE_CONTAINER" and add/change the css and script accordingly, but the attachment editor won't showing up afterwards. I think it would be nice to have this feature implemented in the up coming version of Xenforo as it's really handy. Any help are much appreciated.
