I had an idea like this for a university design (Not really centered in design, more on design methodology and research) class. At first I thought of designing a fully customizable, plugin-based EMS (Like Moodle), then my teacher told me to try and make it bigger, so I designed an app platform where there's only extensions and the UI is fully yours, kinda like Notion Enhancer [1] or Better Discord [2], but without the base app.

Why not build (complex but specific) SaaS applications that just leverage OS designs paradigms on the frontend (taskbar, windows, notifications, desktop, icons..) inside the same tab?
What if the OS-like apps where open plugins that will augment that SaaS?
