I can't find how I can change status bar, title bar and copy comand formatting in foo_columns, maybe I am just blind or something, but if someone could help me, it would be nice

Go to Preferences|Display|Title formatting and do what you need. As musicmusic said not so long time ago, it's unnecessary to implement those to foo_ui_columns, as the core already handles them.

There's even a "go to title formatting settings" button under all foo_ui_columns configuration tabs
