Hi,
Thanks for the interest in our plugins. I can answer your questions.
We do not have a way to hide features such as the iCal if it is a past event.
You could modify the template following our themer’s guide and add a check for the event date and if it is in the past then it would hide it.
We do not have a way to add vetted images or capabilities such as that it could be possible, but with a customization.
The comments rely on the theme, but there might be a way to open them after an event has passed or at least only show on past events.
All these seem possible, but would involving customizations and for the most part that is beyond the support we can provide.
Let me know if you have any follow up questions.
Thanks
