I am sure this has been suggested before and not sure if this is the right place (or whether it should be in wishlist).
Is it possible for someone to develop a GUI Previewer so that when making an new skin it is possible to quickly preview what it is going to look like without having to login to planeshift, or have a "reload Gui/skin" button in planeshift would also be fine. If this was developed it would make creating skins much easier and therefore give more choice to players.
It would also be nice to have a utility that could preview what a texture would look like on an object Ie a new kran skin, or even something small like changing the texture of a stone or a quench tank. This might also encourage people to apply to join the art team
