Are you tired of seeing the same regular instruments over and over? This revolutionary tool that basically does what the Hatter does will help with that!
In all seriousness, the Hatter comes with some restrictions due to the weird implementation of frames, and the way directives are applied to them.
This tool will allow you to easily create any instrument with a custom image up to 96x96, and more experienced modders may also use the output to work with custom drawables anywhere image directives are allowed.
The dimension limit has been set to avoid needlessly big images that can cause lag for (other) players, but may be disabled by going to your console and writing 'avoidRestrictions = true;'.
