Messagebox called before Tk root window creation
Medium Severity
The messagebox.showerror() calls for missing MONGO_URI and MongoDB connection failures occur before root = tk.Tk() is created on line 39. This causes Tkinter to create an implicit hidden root window, which can result in focus issues on Windows, the error dialog appearing behind other windows, or a phantom blank window briefly appearing. Users may miss critical error messages explaining why the app won't start.

Redundant "Messages:" header displayed twice
Low Severity
The "Messages:" header is displayed twice: once as a tk.Label on line 91 and again inserted into the ScrolledText on line 110 via messages_text.insert(tk.END, "Messages:\n\n"). Remove one of these redundant headers.

Unnecessary wrapper frame adds no value
Low Severity
The messages_container frame only wraps messages_text and adds no value. The ScrolledText widget could be added directly to messages_frame, eliminating this unnecessary indirection.

MongoDB URI with credentials exposed in error dialog
Medium Severity
The error message at line 31 displays the full mongo_uri in a dialog box with f"URI used: {mongo_uri}". The README explicitly instructs users to include credentials in Atlas connection strings (e.g., mongodb+srv://user:password@cluster...). This exposes database credentials in visible UI, risking exposure through screenshots shared for support, screen sharing sessions, or shoulder surfing.

Note
Medium Risk
Moderate risk because it changes the app’s core message schema and runtime behavior (MongoDB connection/refresh loop) and adds new UI/state handling; failures could affect sending/displaying messages.
Overview
Enhances the Tkinter chat UI to support per-message usernames and timestamps, switching the message display to a scrollable read-only text area and adding basic window/layout improvements.
Adds input validation (empty/length-limited messages), stores
username/timestampalongsidetextin MongoDB, and improves resiliency with explicitMONGO_URIchecks plus connection and send error dialogs; message refresh remains polling-based with a configurable interval.Updates documentation with clearer install/usage/troubleshooting guidance and introduces a
requirements.txtfor dependency installation.Written by Cursor Bugbot for commit 5bc1ee7. This will update automatically on new commits. Configure here.
