Timeline updates; Engine updates; Bug fixes.
Thanks Diego, I was looking for some button or something that would label a keyframe, or a special type of keyframe that i could move around with a tag in the timeline window to set where i wanted it to go. Its interesting that it's only tied to a master keyframe because if you want to put a tag somewhere in between two other keyframes it appears you need to set a redundant keyframe on one of the other properties of the object in order to create a master keyframe.
Would it be possible to add a trigger action "on tag reached" as well please :)
That already exists in the Timeline plugin as "On keyframe reached".
