Events Short Description to display in Events view, with front-end javascript show/hide toggler

It would be cool to have the ability to create a short description, like an intro text for the events.
Then an option in the Events listing menu, to toggle show/hide quick info for that event, and toggle show/hide to all events at once.

Short description could be working similar to the core content introtext - fulltext, with the read more option.

If users use the read more option, then the event will have fulltext, otherwise only the introtext.

Of course some extra options for introtext characters/words trimming, enable/disable quick info for that view in front-end, could be in the mix...
