This had finally become really useful; I was using it every day for my work, since it let me have multiple panels showing me several web apps at once, with multiple windows for them so I could have them on different monitors, which I kept in full screen mode to maximize my space for them. It was great.
Then they decided to "pivot" and drop most of the features that made it useful for me, instead moving to a web browser extension that lets you easily search multiple services at once (or something like that). That's not what I need, so this is now not a helpful app for me, and the app's description as of the date of this interview is now completely inaccurate.
