Yep. Worst application I've ever had to work with was a WinForms monstrosity where ~300 form elements were used to store the application state, and none of them were named (so it was all "TextBox1", "TextBox2", etc.). Most of the application logic was in a single ~8000 line method. An absolute nightmare to debug or modify.
