There are quite a few feature changes!!
Sidebar rebuilt as a 10-minute grid timeline (drag to select a time range), replacing the old list-and-calendar layout.
Calendar date navigation has been removed — use Obsidian's own file explorer or quick switcher to jump to another day's note.
Added color-coded categories (5 built-in + up to 10 custom), stored as an optional [Category] tag in each Event line.
Simplified the block markers to Event / ToDo / Diary (dropping the leading underscore, which rendered as italics in some viewers).
(Notes written with the old _Event / _ToDo / _Diary markers keep working.)
Added PDF/HTML export for a single day's timeline and To-Do list.
Added a configurable daily note folder (with autocomplete), instead of always using the vault root.
Added automatic UI language detection on first run.
Expanded the settings screen: hour range, daily note folder, language, sidebar theme, and full category management.
