A subtle improvement to this feature exists in the latest release. When you select an element which has a warning associated with it an Options Bar button appears which permits the user to see the warning.
This is a welcome improvement to be sure.
We can also export the warnings to an external file. This is something I posted about in the past and I'm grateful that it has been added.
Phil Read has a blog finally and he recently posted a succinct summary of issues and ideas related to making the warnings that Revit stores in response to a teams work...work better. His ideas are well written and provide insight into the depth of his experience working with many firms over the years. No surprise honestly. Naturally it is easy to agree with his assertions because they make sense and match with most if not all user's experience.
