If you don't know what Spriter is, check this thread:
The construct classic Spriter plugin is in the final phases of development.
As of now, you can expect the spriter plug to behave very much like the standard sprite plugin(minus skew, and distort). You'll be able to stretch, angle, position, play animations, change frames, or play speed, etc, or put behaviors on them. Spriter allows the creation of per frame collision boxes. And these will be separate SpriterCollisionBox objects that are automatically managed, you just test collisions against them when you need to, and they contain all the relvant information about their name, the Spriter object they're a part of, etc.
So what would you like to see besides what we have. The first suggestions I've received are the ability to add tweening, and the ability to take control of a spriter character part in construct, and move it around to make an ik arm, for instance. Both of these features will be added, but id like to see what's most wanted or needed, and prioritize accordingly.
Expect to see the first demo in the coming weeks.
