I saw that when it automatically updated but couldn't be bothered to read what it said. What is the tab grouping again?
You can drag a tab on top of another, and they become part of a group. To see all the tabs in that group, you can press the arrow to expand the group, or you can hover over the group tab and a big square thing pops up showing all the tabs in the group.
It's mostly useful if you open up a million or so tabs. It's a bit annoying you can't see them all at a glance, but that's really just a minor issue for me.
This new version hasn't crashed since installing it, but I've yet to see how it reacts after resuming from standby/hibernate. D:
I think I've replaced saving bookmarks for saving sessions on closing (lazy-bum
)
