v1.0.20

• History storage now takes ~5× less disk space.
• A notification center. Alerts now land in one place behind the bell, with per-type switches in Settings → Notifications — evening recap reminders at a time you pick, meeting reminders, and a heads-up when your history crosses 500 MB.
• Library shows real app icons, so you can see where your time went at a glance.
• Optional Enhanced Search — turn it on to search your history by meaning, not just exact words.
