I had a look at the plugin and have to say, it looks cool. But what's cool now, will be average in a while and then the real issues become clear again. The problem is that you cannot manage or access your pictures/videos/sounds/files from one location because of the underlaying file structure used for Dolphin. Currently all images are written to one directory, and videos to another, etc. This makes handling files resource intensive (for each file we need to check if it's yours and than deal with the different iconsizes to display). Not only is this resource intensive, it is also wasteful. Since all images are placed in one directory (incl the created icons) you will reach the max file locators for that folder and get errors. Because of the extra icons, even four times faster!
So... if the structure of storing user data can be changed it should not be too hard to build a tinymce plugin that does just that (and maybe even more).
The way I see it, it's just another good looking storage for files, that gives me another source to look for things I uploaded in the past. Lets make it simpler instead of even more complicated.
