Built with Electron, the Mobile Template Viewer (MTV) was created as a tool for developers to solve a problem where choosing appearances for NPCs could not be done without loading them into the game.

This was achieved by almost a thousand lines of python to automatically capture images of every NPC in the game, then a view was written in JavaScript to easily sort, view and acquire the appearance names for each NPC appearance. Originally developed as a website, it was eventually packaged as an Electron application for ease of use.
