Dependency-Check Plugin 4.0.0 (and earlier) offers an integration with Dashboard View.
Addition of "Build Time" column to portlets such as "Dependency-Check vulnerabilities per project" would be useful as this would allow one to instantly see that a job with high threat has not been built in a while, or simply confirm that all jobs are current, etc.
The addition of the column should be optional, in case the user decides that the info is superfluous or that the display looks a bit squashed (eg, when using portlets in the left/right column).
The build time is more useful than "Last Success" and "Last Failure" as it provides a single sortable column and because Dependency-Check plugin can generate a report even for a failing build.
The Build Time can already be displayed using the "Latest builds" portlet - but the result can be hard to work with when there are lots of jobs (lots of scrolling up and down).
