Physically clicking the update button is the easy part. That is certainly something that anyone can do, however maintenance isn't that simple. Often times an update will be incompatible with another plugin, theme, or hosting environment. When this happens something will stop working, or in some cases the website will crash completely. Before we make updates, we read the developer changelogs to see what code was updated. This makes sure that the updates will work properly. If we find that an update is compatible, we will notify you and present options to fix or replace that plugin.
