In a helper for a testing environment there was a flag called CheckLayoutConf. The documentation stated: if set checks if the layout configuration is valid and fixes it. I was curious about the validation and fixing mechanisms, so I looked into the code. But if the flag is set, then the layout configuration is just deleted, so in the next start of the program a new default layout configuration is created. Nice "validation" and "fixing" you for there, I thought to myself.
