0.1.0
First release.
One diary-stats code block in a weekly, monthly or yearly note draws the period: which projects it went into, sessions over time, the four weeks of a month, task states, key metrics with a trend, optional goals, and a panel of live links to the days and session logs behind the numbers. The period is read from the note's own frontmatter, so the same block works at every level.
Install by hand: put main.js, manifest.json and styles.css in <vault>/.obsidian/plugins/diary-stats/, reload Obsidian, then enable Diary Stats under Settings → Community plugins.
Needs Obsidian 1.12.7 or newer. Desktop and mobile. The interface is Polish — see the README.
