Tab sidebar independent for each instance

When adjusting the width of the tab sidebar, it changes across all my browser instances. This is disruptive and inconvenient. some of my windows don’t need as wide of a side bar as other windows, and having one window change all my windows is very unintuitive, and is causing me to pick a middle size that is inconvenient for ALL my windows…

Please allow me to select the width of my tab panel independently in each window.

btw: love the side tabs feature!!! :heart::heart::heart: THANK YOU BRAVE!!!
