I found out the other day a plugin I was using had not been updated since 2010. It was causing problems with my WP and when removed, my site sped up. It took a lot of research to find out I had an outdated plugin.
Is there a way that in plugins you can:
1. Include the last update date of the plugin
2. Any plugin that hasn't been updated in a year turns the container orange
3. Any plugin that hasn't been updated in 2 years turns the container red
This is especially important in Multi-site.
