UI Framework	Basic `customtkinter` (Single Window)	Enhanced Single Window (Refined Layout)

The application retains its familiar layout but with significant under-the-hood improvements.

🗂️ Layout: The core button grid layout remains, ensuring familiarity for existing users.
🌗 Adaptive Theming: The data table (Treeview) now adapts to Dark and Light modes, ensuring text is always readable.
🚦 Status Feedback: Operations now provide clearer feedback via popups.

🛡️ Unified Operation Pipeline: A new internal engine (_apply_op) handles all data modifications. This means:
- No more crashes if you click a button without loading a file.
- Automatic UI updates after every change.
- Graceful error messages instead of console tracebacks.
🔢 Numeric Safety: Arithmetic operations (Sum, Mean, Pow) now automatically filter for numeric columns only, preventing errors when trying to calculate the "mean" of text columns.

These operations now modify your dataset in real-time:

Abs: Converts numbers to absolute values.
Cumsum: Calculates cumulative sums.
Pow: Raises numbers to a power (includes a smart dialog for exponents).
Cleaning: Instant removal of empty rows or duplicates.
Mode & Nunique: Now update the dataframe directly (broadcasted values) instead of just showing a popup.

Safe, read-only insights into your data:

Scrollbars: Added horizontal and vertical scrolling to the data view.
Type Inference: The "Replace" tool now smartly detects if you are typing a number or text.
Memory: Large files no longer freeze the UI upon loading.
