When I enter "a" as target page and "ab" as text to display, the dialog should insert [[a]]b rather than the current [[a|ab]]. This should work at least for ASCII-letters. If it's possible to use the localized link trail, this would be even better of course.
Version: unspecified
Severity: enhancement
