An ssb is a completely isolated website. The usecase is to avoid, for one, fingerprinting. The popup window will not do it since you’re running it in the very same browser, regardless what profile you’re running on that browser. The popup thing is just a real estate thing, nothing more. It’s not even a desktop app created with the browser. And like I stated, there are other ways to do what webapp manager does, but it takes more time. The topic was simply a question about “if there were any plans for a qt version of this”. Whether you think it’s important or not to duplicate it is besides the point. That wasn’t the question. Maybe some people would like a webapp manager for the ease of use, but just not a gtk one.
