Problem:
Currently we only support baking every Nth frame. Which sometimes results in more keys than desired, but "cleaning curves" doesn't do the job since most of the time you'd want your original key frames to be returned as a result not a "cleaned up version" of the curves.

Solution:
Add an option to "bake action" named "Smart Bake", which will bake and only return key frames where the user has key framed already.
If the object baked has a constraint target to an other object. The constrain result should be considered in the same fashion it is done now, but only the keyframes that the user inputs in the object baked should be gotten as output.

This will retain the user's original poses or keys in place but depending how sparse the keyframes he originally has are, it will possibly break the interpolation between keys which is expected but should be stated in the tooltip.

Generally using the term "Smart" is not desired since it doesn't really mean anything and people will try to use it without understanding it as if it was intrinsically better. Maybe something like the terminology used in autokey would be more descriptive:

I agree. Anytime I heard "Smart Baking", I assumed it always did more than what I implemented. Rig On the Fly does more and includes the constraint targets for the bake frequency. They can do more because they only deal with rigs they've defined and created. A potentially simple solution for us is to add support for Baking sets (or selection sets?.. or just general bone sets that operators can use) and if a bone is part of the set, then it's baked where other bones of the same set are keyed. Ideally, riggers would create these Bake sets since they know the rig in and out.
