It's all in the subject really. Moving platforms can be a bit fiddly when solved with trigger-collisions, and keeping the combined momentum of the player and the platform when exiting its trigger is also not easily done in Game Creator (as far as I know). An official solution as part of the traversal module would be much appreciated (perhaps even with support for hanging on ledges etc).
Of course, the whole concept of moving platforms can be a bit silly, but it is nonetheless a staple of videogaming.
