For text fields in the tracker definition, the project admin can validate the entry via regular expression (which is a cool feature).
When the entry doesn't match, the TF UI creates a red cross beside the field.
There is no explication about this red cross. Users are sometimes confused.

It would be great to display a help text when the user hoovers with the mouse over the red cross, e.g. "Your entry doesn't match the field validation pattern 'artf\d+'"
