The primary function of the UXP Developer Tool is to provide a centralized interface for managing UXP plugins. Historically, developing for Adobe was a cumbersome process involving manual file manipulation and obscure configuration files. UDT streamlines this by offering a clean dashboard where developers can "load" unpacked plugins directly into the host application. This hot-reload capability significantly accelerates the development cycle. Rather than constantly restarting Photoshop or navigating deep system folders to test minor UI changes, developers can toggle a plugin’s state instantly, fostering a rapid iteration loop that is standard in modern web development but was previously foreign to the Adobe ecosystem. | Error | Likely Cause | Fix |
