1. Grouped TOC Loading

• Current Approach:

  • The visibility of the entire comic/EPUB TOC is controlled by the content button.
  • Hiding the TOC significantly improves reader performance, but it also makes the TOC inaccessible to the user.

• Suggested Approach:

  • Load all TOC entries as usual.
  • Divide them into groups of 100 entries each. (Depends on number of file entries, and not chapter numbers)
  • Display each group under a label (e.g., 0+, 100+, 200+).
  • Clicking a group label toggles the visibility of that group’s entries.
  • Only one group can be active at a time.
    • Hidden groups should have no impact on reader performance, similar to fully collapsing the TOC via the content button.
  • This might eliminate reader performance issues with very large TOCs and also make the TOC accessible at the same time.
  • Erring on the side of caution, each group should contain a maximum of 100 TOC entries.

Scenario when this would be used?

• Eliminate reader performance issues from large TOC's by showing only the active group.

Supporting information

• Divide files in a comic/EPUB into fixed ranges:
  • 0+ → Files 1–100
  • 100+ → Files 101–200
• Used “0+, 100+, 200+…” format (preferred over “0–100, 101–200” for clarity and UI consistency).
• Grouping is based on files, not chapters, because chapter numbering can be inconsistent (e.g., Chapter 0, 1, 1.5, 1.6, 2, 2.5, 2.6, etc.).

---

• The pin/unpin icon for the reader side list has been moved into the side list panel for easier access and a distraction-free experience when unpinned.
• Previously, the pin control appeared over the comic/EPUB content because it was positioned beside the side list.
