Yes, we have plans to add more interaction options but still need definition to be included in our prioritization. Interactions and animations are capabilities that tend to be infinite so we need to be smart at a product definition level. Last big changes related to interactions were at the 1.9 release but we also added another related feature recently. We are still deciding what should be the next step and more triggers could be an option.
We are already gathering info from users at interviews and direct requests to understand the most urgent needs to be addressed and we will definitely keep an eye to this post and its replys.
