Both as a resource moderator for SpigotMC and working for a business that runs website SEO scans, I’ve found that there are a lot of repetitive tasks. Most of these involve filling out details in a form. For example, about 75% of the reports on resources for Spigot plugins were “invalid”. Either they were making a comment about the plugin itself (intended for the author), or they reported the resource with no proof (i.e “this plugin is stolen”) or source. I would have to write the same stuff each time as a response.
You can also use it if you want things like a better menu system for your favorite websites. You could add a button that switches the background colors (dark/light), or a button to remove all the annoying elements (like a reader mode).
