Implement a function warning that (optionally) highlights a Math Region and displays a message when the user either hovers over or the region or clicks on it. The function would be akin to the existing function error except that, unlike the latter, warning would not halt worksheet evaluation.
It's something I've often felt would improve a function's usability. It might also have proved useful for highlighting the effects of partial application (and thus mitigating the need to remove it on the grounds that it confused some users).
Here's a rough example of warning's potential use:
Zoom in to display
Warning and error history - just another thought ...
Maybe a function Notifications that presents a list of warnings and errors together with the identity of whatever raised the error/warning? Mathcad Monads ...
