Okay, I know this is a weird, super niche, and kind of ridiculous question, but who doesn't want to have their cake and eat it too? Basically, I want two browser windows open, when I open a tab, or switch a tab in one window, it does the exact same thing in the second window. Maybe someone knows if this is possible. Since I'm sure you are scratching your head right now, I have a multi-monitor setup, two horizontal and one vertical. At any given time I have 6 to 10 windows open across the three of them, and another 10 to 15 windows minimized (and for what it is worth, currently 132 tabs, but that's about to go up after I finish this post). In some cases I work off of lists, and in all cases I have so many tabs open TreeStyleTabs is a must. For working off a list, or for navigating between tabs, a longer vertical window is preferred; however, for working on an account or using portals a wider horizontal window is usually preferred, with some exceptions. I'd love it if I could get the best of both worlds, have the same window on two monitors, that way I can use the vertical aspect of it to reference my lists, and open/navigate between accounts, but actually work on the accounts on my horizontal window. If this is impossible, I won't lose sleep over it, but if this is possible, omg is my productivity going to go up by like 1%, which is around 30 to 45 minutes a week, that's like over a free day of work a year.
