The information in this tab is based on that which could be taken from Optimizely. Keep in mind, however, that this information refers to the visitor of the site, not to the Optimizely user himself. I only say this to avoid misunderstandings.
The events tab helps you when it comes to checking and customizing events. It is also the only tab that doesn’t exchange information completely on every page view, but provides you with information about events across pages.
The Simple Mode of MOPPI is designed for users who only want to see which experiments are active on a page and which variations exist for these experiments and to which of these variations they have been assigned.
When the icon is blue, Optimizely runs on the page. A number in the lower right corner additionally shows the number of running experiments. Remember that it may take a second or two for the icon to update its color.
