Plug-in Usage is not tracked at all & it would be very helpful to have the date a plug-in was last run/generated/used added to the Home › Tools › Plugins screen. It has a "Last Updated" column which is helpful, but this information would also be useful. Alternatively, it would be great to have this added to the system logs like the cronjobs are.
Good idea. I think this should be limited to hooks tools and report. Other hooks like intranet_js would generate too much entries. Or let the plugin decide what to log ?
I was worried about the same thing as you Frido, creating too many entries. We could tie it to a system preference maybe, but I also like the idea of the having the plugin decide what to log.
