What's New
The program now looks for subfolders in the "devices" folder, so you can separate devices by source or function. All the previous devices I've made have been included and moved into the "default" subfolder.
Devices can be mirrored across the X and Y axes.
The "No Texture" checkbox has been replaced with a "Raised Detail" checkbox. When unchecked, the program will automatically "flatten" the image to a single color. Pixels with a color magnitude below 50% will be set to transparent. What this means is that custom devices no longer need a "flat" image and a "detail" image.
Edit - Update 0.81
Corrected a typo in the elements dropdown.
