 Minor Revisions:
  - Improve Deduplication Algorithm with Advanced Option Settings (Implement Chapter & Author-based Comparisons, Resource Intensive)
  - Integrate Download Directory Changes (Settings)
  - Investigate feasibility of Multi-Page Screenshot (Reader)
  - Add Hover Info on Library (Make sure doesn't conflict with additional clicks)

 In-Progress:`
- - Fix Reader Chapter Shifts (Glitched Sentinel)
-   - Still Shifts Down after reading ~8+ Chapters?
-   - Identify When Chapters are Unloaded, How to Preserve Structure
+ - Enable Cloudflare Bypass (Suwayomi Config) (Requires Patching)
+ - Fix NSFW Parsing (Appears to not Work???)
+
+ - Check & Fix Zoom System
+    - Incredibly zoomed in on Windows (Appears to work fine on 1440p)
+    - Zoom Values are Incorrect
+    - Global Zoom should only scale Reader UI, not Manga

+ - Fix Resume-from-Read
+    - Start on Chapter 46 -> Go all the way to Chapter 47 (Page 28)
+      - Results in Opening Chapter 46 to take to last page of Chapter (Cache not Cleared).
