 ## 2025-02-28 - Structured CLI Reports
 **Learning:** Dense numerical data in CLI output is hard to parse. Using ASCII box-drawing characters and alignment to create a "dashboard" or "invoice" style summary significantly improves readability and perceived quality.
 **Action:** When summarizing simulation or batch job results, always format the final report as a structured table or box rather than a list of print statements.
+
+## 2025-03-01 - Progress Visualizations
+**Learning:** For long-running CLI processes, particularly those that suppress verbose logging (e.g., `--quiet`), users can be left wondering if the program has stalled. Adding an interactive, dynamic progress bar using `\r` provides critical system status visibility without polluting standard output logs.
+**Action:** When creating CLI tools with potentially long execution times or loops over large data structures (like Pandas DataFrames), implement a simple dynamic progress bar, conditional on `sys.stdout.isatty()`.
