Highlights

• Native popup experience: Clicking the extension icon opens a compact Chrome popup instead of a separate window.
• Manual + imported deadlines: You can add custom deadlines or import recommended conferences from CCFDDL.
• Official site shortcuts: Imported conferences retain homepage links, and added cards can open the conference website directly.
• Calendar handoff: Right-click saved or imported cards to send a deadline to Google Calendar or download ICS for Apple/iCloud and other calendar apps.
• Bilingual UI: Switch between Chinese and English from the bottom toolbar.
• Display preferences: Choose a display time zone, switch between 24-hour and 12-hour, and change date order between YYYY/MM/DD and MM/DD/YYYY.
• Local-only data: All data stays in chrome.storage.local, with no account or cloud sync.

Customization

• Language: Toggle between Chinese and English from the popup footer.
• Time zone: Switch deadline display between supported time zones. The default is Asia/Shanghai.
• Time format: Choose 24-hour or 12-hour (AM/PM) in the settings panel.
• Date order: Choose YYYY/MM/DD or MM/DD/YYYY.
• Calendar actions: Right-click a saved or imported deadline card to open the calendar menu.
