TST does look great. Not sure it's usable in my case: - similar to what others mentioned, I'm running a browser at 50% width of fullscreen (27", 4K display). This is ideal for most websites: it's about as narrow as most websites would natively be. However, this means there's no horizontal space left to sacrifice. - I've been hard at work eradicating non-standard/exotic tools/workflows/etc. from my life. Maintainers abandon software regularly and then you're left stranded, perhaps your entire workflow gets turned upside down. Good old regular tabs "just work" and do so everywhere. The more you customize your setup, the more you're stranded on foreign territory. There's value in just getting used to what's there by default, to a degree. TST essentially turns the 1D tab row (let's call it list) into a nested structure. And that really is fantastic. However, I think I'd hope and wait for that to become mainstream and officially integrated and wide-spread, if ever, before relying on it. The usual, top-row tab bar with some 2-dimensional twist seems promising.
