Superagent 1.7.18
Adding a folder to a group showed nothing. The new project became the active one and then sat there as an empty pane, because a project with no conversations has nothing to draw and clicking it deliberately does not create one. Adding a project is not looking at a project — it is asking to work on it — so it now opens with a conversation, and you land in it. Clicking a project you already have still never makes one.
The relay's daily usage is in Settings → Phone. "12 MB of 500 MB. Resets at midnight UTC," with a bar that reddens near the ceiling and a line saying what spends it: mirroring a page or the simulator, not the conversation. The relay has been sending this every megabyte for two days; the Mac was throwing it away. It matters because reaching that ceiling stops everything reaching the Mac, and until now the only symptom was your phone saying it could not find it.
Activity, in the sidebar. The same switch the phone has. Projects is the tree you know; Activity is every conversation on this Mac in one flat list, newest first, with the project as a subtitle. The tree answers "where is that conversation"; this answers "what happened while I was away".
Also: one reload button in the browser toolbar instead of two lookalikes, back/forward/reload drawn as icons rather than punctuation, and the iOS Simulator can be turned on its side.
