I actually wrote that tool based on a huge frustration I had going back and forth to the browser, and not being able to work while being agnostic to the services, which felt being a totally broken UX. I have then worked on that tool for a while, used it and refactored it a lot up until I'm happy using it.
All in all, when I'm doing a tool, I'm first doing it for myself (I might invent the DIFY concept, to override the DIY concept )… only then I'm sharing it with others.
