What

It would be useful to list the names of all plugins updated in the Activity Log

How

For plugin updates, the Activity Log currently lists the names of a limited number of plugins, with something like "and 6 more," depending how many additional plugins were updated at the same time.

Example:

It would be extremely helpful to list out all plugins that have been updated, rather than this truncated version. While the names of the plugins not mentioned by name might also be tracked in other sources – depending on the host – it would be extremely useful to have all the plugin names displayed in the Activity Log.

This would reduce the need to visit multiple spots to get the required information, making the process of troubleshooting – for example – more efficient.
