(Editor) Reload Spritesheets?

[TheBearWannabe]

I've been working on custom pixel artwork for my project, and in order for my existing spritesheets to update I need to manually close and re-open the editor application for it to appear. This is fine, but is there any refresh function within the editor to reload existing elements?

There isn't but I recall this feature being requested before. I'm not sure if there's an official feature request for it open though.
