Edge has shared browser "workspaces", I use them solo to have different browsers for different roles. Like a workspace for project A, another for intranet, another for project B, ... the main thing about it is all your tabs are where you leave them and it's a bit more visually manageable than TST which I use at home. Basically means you can have lots of tabs open, but now in different windows (with different colours!).

That feature is supposed to be about 'multiplayer' and has been so good it actually makes me want to see Muddy just because of how positive that 'multiplayer' has been. Weird, huh.

Aside, I'm still mourning Opera Unite.
