The Opera GX sidebar is really useful, but it feels kinda limited right now. It would be awesome if we could get more built-in sidebar apps, or even better, the option to add our own custom apps using a link or web app.
This way, we could put stuff like Spotify Web, Notion, Google Translate, school websites, or game tools straight into the sidebar without opening extra tabs. It’d make multitasking way easier and keep the browser cleaner.
