Mind Map History and Management

Mind Map Wizard offers a robust generation history feature, ensuring that all your created mind maps are easily accessible and manageable. This functionality is designed with a strong emphasis on user privacy, as all data is stored exclusively on your local device within the browser's localStorage [Local Data Storage and Privacy].

Automatic Saving of Mind Maps

Every mind map generated using the AI is automatically saved to your browser's local storage. This ensures that your work is persistently available even after you close the application or your browser.

The saving process is handled by the saveMindmapToHistory function in scripts/new.js. When a mind map is successfully generated, the following information is stored:

• Topic: The original topic or title of the mind map.
• Markdown Content: The raw Markdown text that defines the mind map's structure.
• Timestamp: The exact time the mind map was created, used for sorting and displaying how long ago it was generated.
• Unique ID: A unique identifier for each mind map, allowing for individual management.

To prevent an excessive accumulation of data, the history is capped at 100 mind maps. When this limit is reached, the oldest mind map is automatically removed.

Accessing Your Generation History

Your mind map history is readily available through the left sidebar of the application.

1. Loading History: The loadMindmapsLeftSidebar function in scripts/new.js retrieves all saved mind maps from localStorage and populates the sidebar list. Mind maps are sorted by their creation date, with the most recent ones appearing at the top.
2. Mind Map Display: Each entry in the sidebar shows the mind map's topic and a human-readable timestamp (e.g., "Just now," "5 minutes ago," "Yesterday," "3 days ago"), formatted by the formatDateLeftSidebar function. Titles are safely escaped using escapeHtmlLeftSidebar to prevent rendering issues.
3. Loading a Specific Mind Map: Clicking on any mind map item in the sidebar (which triggers the openMindmapLeftSidebar function) will load and display that mind map in the main viewer, along with updating the URL with its unique ID using updateUrlWithId.
4. Searching History: For quick retrieval, you can open a search popup by pressing <kbd>K</kbd> or clicking the search icon. The openSearchMindmapsPopup function initializes the search interface. As you type, the filterAndDisplayMindmapsInPopup and renderSearchMindmapResults functions dynamically filter and display matching mind maps, allowing you to easily find specific entries. Clicking an item in the search results (via openMindmapFromSearchPopup) will load it.

Managing Individual Mind Maps

The left sidebar provides direct management options for each mind map in your history.

Renaming Mind Maps

You can rename any saved mind map to better organize your history.

1. Initiating Rename: Click the "Rename" button (pencil icon) next to a mind map in the sidebar. This calls renameMindmap(id) in scripts/new.js.
2. Rename Popup: A popup dialog appears, pre-filled with the current title of the mind map. This dialog is handled by customPopups.openRenamePopup.
3. Confirming Rename: Enter the new name and confirm. The updateMindmapInStorage function updates the topic field of the mind map in localStorage.
4. Update Display: The sidebar automatically reloads to reflect the new name, and if the renamed mind map is currently displayed, its title will also update.

Deleting Mind Maps

Individual mind maps can be permanently removed from your history.

1. Initiating Deletion: Click the "Delete" button (X icon) next to a mind map in the sidebar. This triggers deleteMindmap(id) in scripts/new.js.
2. Delete Confirmation: A confirmation popup appears to prevent accidental deletion, managed by customPopups.openDeletePopup.
3. Confirming Deletion: Upon confirmation, the mind map is removed from localStorage. If the deleted mind map was currently displayed in the main area, the display will be cleared, and the application will return to the initial state.
4. Update Display: The sidebar is automatically updated to show the revised history.

Clearing Entire History

If you wish to remove all your saved mind maps and related local data, a "Clear History" option is available.

1. Accessing Clear History: The clearHistory function in scripts/mmw.js initiates this process, typically linked to a button in the UI.
2. Confirmation Popup: A prominent confirmation dialog appears, emphasizing that this action is irreversible.
3. Confirming Clear: If confirmed (via confirmClear), the following items are removed from localStorage:
   • mindmap-history: All saved mind maps.
   • mindmap_local: (Legacy/Fallback)
   • mindmap-playground: Temporary or playground mind maps.
   • lastMindmapInput: The last input text used for generation.
4. Reset Application: After clearing, any existing URL parameters (like q or id) are removed, and the page is reloaded, returning Mind Map Wizard to its initial state.

These features collectively provide comprehensive control over your mind map history, offering a private, fast, and organized way to manage your AI-generated knowledge.
