I have the Action Browser docked to the right of the Graph View. I pick an action from the AB and I notice that it's already lagging to catch the action. It feels very unresponsive. Sometimes I need to pick, drag and drop thrice before the action is deposited with its own state in the FSM.
On a side note, this latency is somehow mirrored (and might be related to this) when trying to move actions up and down inside states. It's not sluggish but finicky in that it does not respond very well and will often ignore a click or a move. I just wish that overall it didn't seem to be so... misresponsive?
