I welcome contributions to MasterCopy. Until this project is up and running and there is better documentation of the goals and engineering standards, I recommend that you send me an email with a feature proposal before starting major work. This will avoid disappointments in pull requests that don’t get integrated.
The following are some areas for future development.
Cross-platform Testing and Continuous Integration. Right now MasterCopy is tested on a few versions of a few browsers. It would be nice if there was some automated way to test it on more browsers.
Ideomatic JavaScript, HTML, and CSS. The code should follow best practices for JavaScript, HTML, and CSS.
Make UserInterface.js more general. It should be easy for someone to build another version of MasterCopy, reusing UserInterface.js. As an example, consider a version that performs three transforms of three images for projecting onto the three visible faces of a cube. Instead of adding this feature the MasterCopy, it should be possible to write another simple HTML file that would leverage most of the code in UserInterface.js.

More rational directory organization
Consider using Hugo to build GitHub pages. If we did this, the MasterCopy application would just be static content.
Fix Bugs. I will enter bugs in the GitHub issues list shortly.
Fixed Aspect Ratio Cropping Rectangle. Suppose you have a 2:3 image that you would like to transfer to a 4:5 canvas. You’d like to crop the image, instead of stretching it. MasterCopy is able to generate a 4:5 rectangle (or whatever you request) that can be moved and resized in crop mode. This is probably just the red rectangle that today marks the border of the user’s image.
Image Processing It would be nice to load one image and then adjust curves and perhaps do edge detection in MasterCopy. Then one could load a photograph and generate a version that shows detail in the darks and another that shows detail in the lights.
Imagine projecting onto the front of a building, the three faces of a cube, or perhaps onto a white theater set. Trees and other obstacles prevent you from putting the projector directly in front of the building, so you are using MasterCopy to eliminate distortions so that it looks as if the projector was right in front.
IFrame Mode Instead of loading an image, display an iframe that can show any user content, including video. UI could be a popup window where the user enters the url for the iframe, or they might be able to just drag/drop the url into the iframe.
Cropping Regions Consider the following scenario: You are setting up a video installation and want to project a video onto the triangular front of a gable on a house. You don’t want the projector to light up any area outside of the triangular front. After aligning the artwork in MasterCopy, you enter cropping mode and use a set of simple tools to draw an arbitrary cropping mask. This could be a polygon or it could include splines (e.g. to allow for circles). In design mode, the cropping region would be semi-transparent so that it was easy to see if artwork was being cropped away. Outside of design mode, the crop would be black.
Load and Save Cropping Regions There should be some way to save cropping regions, either to some sort of isolated storage or cookie, or it might load the clipboard with some text that the user could save in a file that could be loaded in the future. Could generate a data file or the html source for the session.
Multiple Projections Imagine projecting onto the three visible faces of a cube, or the back and side walls of a theater set. It would be nice if one could add additional perspective rectangles to MasterCopy and then align each one. This would allow one projector to display three images on the three visible faces of a cube.
