When looking through the file manager, we can save an extra click if we have the ability to hover over an image to show the name of the image. Right now, we have to click properties for every image... which is time consuming
In file manager we have the ability to hover and see the file name. But this is not there in file picker which you use to insert file into the article. We are currently in the process of improving file manager, we will add this as well.
@Vishnu: The real use case is when we want to insert the image. That's when we need to see the image name. Going to the file manager first, and then finding the image, and then again navigating to it in the insert menu isn't really very usable. I think you understand that. This functionality must be available as close as possible to the point of use.
