You (the project manager or WP admin) are constantly needing to tell your developer that you added/updated/removed a plugin 
on the live site so he can keep his dev environment semi-synced. This eliminates that need, by just shooting them an email 
with the plugin information and what happened.

Plugin Notifier

Automatically alert your developer when you install/update/remove a plugin.

Time to Update sends you a nicely formatted email notification whenever updates are available for your WordPress core, installed plugins, or themes.
For security conscious site owners who want to keep their site up to date, Time to Update provides a simple, lightweight, and set-and-forget solution. It ensures you never miss a critical core security patch or a plugin update just because you haven’t logged into the dashboard lately.
The plugin runs quietly in the background using WordPress cron. It uses standard WordPress update channels and does not rely on third-party SaaS services.
