Hey great plugin, very useful so thanks.
I think I may have found a small bug which I am able to replicate consistently. Basically the "File Name" next to the small image thumbnail does not update until after you have made 2 edits to the title. The actual image filename DOES actually rename as expecte.
So for example:
1. I upload an image
2. I rename the image to "a" and save. The "File name" at the top above "File type" still shows the old image name (but actual file name has changed properly).
3. I rename the title to "b". "File Name" now updates and changes from old filename to "b".
Not sure if this is just me, could be one of many things going on in my installation :)
One more thing if you don't mind. Is it possible to set a limit on the title input field? If I change the title to something very long, the filename also changes as expected to a huge long filename.
