A theme that follows your system, a presence indicator that says something, and an extension that asks for far less than it used to.
New
Light, dark and system themes. Pick one or follow the operating system, and it is remembered between sessions.
Improved
Presence you can read. The connection indicator says how many people are in the room, or that you are offline, where it used to be a coloured dot you had to interpret.
Narrower permissions. The extension injects into the tab you activate it on rather than running a content script on every site you visit. It sees the pages you point it at, and no others.
Do not lose unshared work. A warning before you close a tab holding annotations that have not been shared yet.
