Calendar: Add option to hide Memos/Tasks pane
The UX experience is not consistent between the Mail and Calendar panes. Specifically, in Mail, you can hide the "To Do Bar" via the menu bar. The similar "Task Bar" does not have such an option (but should). See this SO post for more info.
I have version 3.40.0-1 on Ubuntu Linux 21.04.
