-tkinter_ui.py (v0.5)
---------------------
-Improved teaching Tkinter UI for SchedPlus.
+tkinter_ui.py (v0.5 - DB compatible MVP)
+----------------------------------------
+Minimal compatibility update for the new DB-backed scheduler.
 
-Still intentionally simple, but with cleaner layout,
-better spacing, and more readable structure.
+Full UI overhaul will happen in a separate issue.
