🔧 HOW IT WORKS:
|
||||
|
||||
1. CONTENT INJECTION (content.js)
|
||||
├─ Runs on every webpage (all_urls match)
|
||||
├─ Makes text elements contenteditable
|
||||
├─ Adds visual styling with styles.css
|
||||
├─ Detects blur events and auto-saves
|
||||
├─ Loads saved edits on page load
|
||||
└─ Monitors for new dynamic content
|
||||
|
||||
2. STORAGE (chrome.storage.local)
|
||||
├─ Key: "page_edits_<base64_encoded_url>"
|
||||
├─ Value: { element_id: new_html, ... }
|
||||
├─ Persists across sessions
|
||||
└─ ~10MB limit per domain
|
||||
|
||||
3. POPUP INTERFACE (popup.html/js)
|
||||
├─ Shows edit count
|
||||
├─ Save all changes button
|
||||
├─ Clear all edits button
|
||||
├─ Export edits as JSON
|
||||
└─ Keyboard shortcuts guide
|
||||
|
||||
4. BACKGROUND SERVICE WORKER (background.js)
|
||||
└─ Minimal - mostly handles popup interactions
|
||||
|
||||
═══════════════════════════════════════════════════════════════════════════════
|
||||
|
||||
⌨️ KEYBOARD SHORTCUTS:
|
||||
|
||||
Ctrl+S (Cmd+S on Mac) Save current edit
|
||||
Ctrl+Shift+S (Cmd+Shift+S) Save all edits on page
|
||||
Click Edit any text element
