It would be nice if the selected texture/s in texture Packer could be hilighted a blue color, like the empty space is currently hilighted in red. This would make it easier to identify textures that are quite similar in appearance.
It would also be good if there were hotkeys for "Save Project" (CTRL + s) and "Export Texture" (CTRL + e).
It would also be really nice if the program did not bother you with "Do you want to overwrite?" when exporting textures.
I feel these improvements will benefit all users of Texture Packer and help them to be more productive.
