Reviewer's GuideRefactor create_root to use a tkdnd.TkinterDnD root with dark mode and a main_frame layout, reparent all widgets under this container, integrate drag-and-drop support with new handlers, and remove unused NSFW filter code.

There was a problem hiding this comment.
Hey there - I've reviewed your changes - here's some feedback:
- create_root has become very long and mixes UI layout with event binding—consider splitting it into smaller helper functions for better readability and maintainability.
- There’s a lot of repeated drop_target_register and dnd_bind code—extracting a helper to register DnD handlers would reduce duplication.
- The create_root return annotation still mentions ctk.CTk but the function now returns tkdnd.TkinterDnD.Tk; please update the type hint to match.

**suggestion (bug_risk):** handle_drop_source does not sanitize or validate file paths beyond extension.
Please add error handling for invalid, inaccessible, or corrupted files to ensure robust file access and image loading.
```suggestion
def handle_drop_source(event):
"""Handle files dropped on source button or label"""
file_path = event.data
# On Windows, file paths may be enclosed in {}
if file_path.startswith("{") and file_path.endswith("}"):
file_path = file_path[1:-1]
if not is_image(file_path):
update_status("Please drop an image file for the source.")
return
# Check if file exists and is accessible
if not os.path.isfile(file_path):
update_status("File does not exist or is not accessible.")
return
try:
# Try opening the file to check for accessibility/corruption
with open(file_path, "rb") as f:
data = f.read(10) # Try reading a small chunk
modules.globals.source_path = file_path
global RECENT_DIRECTORY_SOURCE
RECENT_DIRECTORY_SOURCE = os.path.dirname(modules.globals.source_path)
try:
image = render_image_preview(modules.globals.source_path, (200, 200))

update_status("Failed to load image preview. The file may be corrupted or unsupported.")

source_label.configure(image=image)

**suggestion:** No error handling for video preview rendering failures.
Add error handling to render_video_preview to catch exceptions and inform the user if preview generation fails.
```suggestion
elif is_video(file_path):
try:
video_frame = render_video_preview(file_path, (200, 200))
target_label.configure(image=video_frame)
except Exception as e:
import tkinter.messagebox as messagebox
messagebox.showerror("Preview Error", f"Failed to generate video preview:\n{e}")
target_label.configure(text="Video preview unavailable", image="")

**issue (code-quality):** We've found these issues:
- Split conditional into multiple branches ([`split-or-ifs`](https://docs.sourcery.ai/Reference/Default-Rules/refactorings/split-or-ifs/))
- Extract duplicate code into function ([`extract-duplicate-method`](https://docs.sourcery.ai/Reference/Default-Rules/refactorings/extract-duplicate-method/))
