What this page is
The one plan you are working to, with its progress and its own planning chat.
Open Month in Linxi, then Master Plan in the panel list beside it. It has its own address, /my/calendar/master, so it can be bookmarked or sent to somebody directly rather than described as a series of clicks.
A look at it
A walkthrough of this screen — what is on it and what each control does — is being written. Until then the page itself is one click away.
