First off, I am new enough to ASP that simple things still stall me, but not so new that I missed the 5.5. to 5.6 upgrade. heh
So with that, I've a few questions and searching for advice:
I've a project that uses layers bound to bones exclusively with the only point interpolation being between hand shapes in switch layers. The trick is to keep the various joints lined up so I've been moving origin points to coincide with where the bones pivots will eventually go. I've also made a little target shape to add as a new object to each part (wrist to hand, etc) out of necessity because copying that target from one layer to the next almost always shifts around a bit. Reading the forums here, Vern said something about using Duplicate vs Copy/Paste which will certainly help when the full layer is copied, but is there a way to make copying only one object from one layer to the next behave a bit more?
I've been placing the parts (foot to ankle, etc) by lining up the little targets, and rotating the layer (Key 3) to get the angle right. But is there any advantage to setting the layer rotation to zero and rotating the points instead? Also, is there any way to move the origin point of a selected group of points?
Also, I notice that a vector layer in a switch layer, copied to a new layer and modified (translate points) while still in the switch layer seems to revert to the original point configuration as soon as the timeline reaches frame 1 and beyond. So I presume there is a reason for it happening, but is there a way to turn that off? Sure its only a few extra steps to move it out of the switch layer, edit then drag it back, but I've a lot of points to push around and I'd like to shave time wherever possible.
Thanks in advance...
Edit: Never mind about the third question: Duplicating the vector layer while inside the switch (as opposed to Cut/Paste) gives me a clean layer (no embedded animation in the points) to work with. Thanks Vern!

Edit: I forgot two more questions... Sorry!
What does the little red dot indicate in the layers list, next to the shape icon? Seems like I read it somewhere in the old docs last year, but I cant seem to find it now.
Also, I have a few keyframes in an otherwise empty timeline that simply wont delete? They appear almost at random amongst the layers, and always at frame 1. They represent the unselected points motion and the unselected points curvature.
And why is it that some points that have been angled using the curvature tool cannot later be returned to smooth? The result is usually a gap in the line, especially if the line width is cranked up a bit.
Which reminds me.. Is there a way to *really* weld the endpoints of two separate objects together? I can move and weld the points together and get that nifty little click sound, but they still seem to be two separate objects as evidenced when I click the "new" object with the Select New Object tool and only half of the object turns red.... Just wondering.
