The toolbar popup
Detailed settings page: seven tabs that lay out every detail.
| Tab | What you do there |
|---|---|
| Home | Master switch, current scheme, animated backgrounds, opacity — with live preview |
| Schemes | Browse the 17 built-ins, create / edit / delete custom schemes, restore hidden presets |
| Schedule | Add and edit time slots; switch schemes on a schedule |
| Animations | Toggle each of the 9 effects, tune parameters and colours, with live preview |
| Site rules | Whitelist and per-site schemes |
| Import / export | Export a JSON backup, import a scheme someone shared |
| About | Version, supported languages, privacy policy |
Two levels of switches — do not mix them up
This is the most common confusion, and it disappears once stated clearly:
| Switch | What turning it off does |
|---|---|
| Master switch (top of the popup / top of Home) | Stops the colour scheme and the animated backgrounds together; every page returns to its original look |
| Apply scheme | Removes only the colour layer (gradient / frosted glass / blobs / dark), while the animated backgrounds keep playing |
In other words: you can run no colour at all and still let snow fall across the page.
Defaults after installation
| Item | Default |
|---|---|
| Master switch | On |
| Mode | Scheduled |
| Schedule | 06:00 → Green Field Warm Sun; 18:00 → Dawn Eye Care |
