Powerpoint is a part of it, but its not the conductor for me.

At least in my case, its because only portion of the media is static prior to tbe presentation. Some is adhoc, or last minute additions, and any presentation oftenchanges its order might change on demand.

So ill run a powepoint of sponsors, as the core, and someone says "run promo video 4" because the want to talk about sponsor 4 now., or "sponsor 18 just walked in, run their video to make em feel special."

The flow and ad hoc nature made me wish for a console like fox sports or something, to move items in and out of the big screen.

Some stuff, like winners of raffles, are discovered moments before i throw em onscreen. Those i handle a bit different, but its ebb and flow of events that make me want something not so developer oriented.
