I do all the time because the feature exists. I would treat it like a sliding line in my tabs bar. When I'm done with a tab for now it goes to the right, and eventually everything to the right gets closed once I haven't used it in a while
I do. I open a search page, middle click a bunch of links, then want to close all of the ones to the right because I found one that told me what I needed and don't need the rest of them.
Probably a perfect example of why it's so useful for developers to talk to users
Not only to understand the usage of features, but also use cases perhaps to design even better features
It's useful when starting a thread of research of research as new tabs will be opened to the right (Ctrl+Clicking a link). So after it's done, close to the right can be quite useful.
