And it is damn good text editor. But this is what i do really often. I have project folder with lots of images (for example textures). I need to use some of them, and i have them listed in the sidebar. Wouldnt be faster for the programmer to see them directly (which image what is and its parameters) ? Instead of opening explorer again, going to taht directory and viewing them there (5 more actions, but stacking 100 times make 500 usless actions).
I understand it is text editor, and you are right about that. It is just a feature i and i am shure many other would benefit of.
