Edupage Extras от JustAlex

Edupage Extras adds quality-of-life features on top of the EduPage school
portal (edupage.org) — themes, smarter grades and attendance, and timetable
tools — without touching your account, credentials, or grades on EduPage's
servers. Everything runs locally in your browser, reading data that's
already on the page you're viewing.

APPEARANCE
• Several color themes for the EduPage interface, plus a custom theme builder
• Optional keyboard shortcut to toggle themes
• Centered layout and clean-UI tweaks (e.g. hiding the help banner)

GRADES
• Grade badges and color-coded average bars on the grades page
• An overall average row, calculated from EduPage's own per-subject averages
• A Virtual Grade Calculator — type in hypothetical grades and see
the projected average update live, using EduPage's own grade weights
• Export your grades table as JSON

ATTENDANCE
• Per-subject absence percentage and lesson counts on the grades page
• Exact current-halfyear absence percentage, pulled from EduPage's own data
• Adjustable halfyear date boundaries in Settings

TIMETABLE
• Substitution and room-change highlights are colored by type instead of
EduPage's single generic color, so you can tell at a glance what changed
• Export your current week or whole half-year timetable as a standard .ics
file, importable into Google Calendar, Apple Calendar, Outlook, and more

LANGUAGES
English, Slovak, and Czech are bundled, following your browser's language
automatically.

PRIVACY
• No login, password, or account access — the extension never sees your
EduPage credentials
• No backend server and no analytics
• All grade/attendance/timetable data comes from the EduPage page you already
have open; nothing is sent anywhere except an optional GitHub check for
extension updates
