Yeah, the savepos/reset commands is pretty unfriendly. I think the
sensible fix is that "reset" should be changed to move unknown models in
some sensible way instead of just leaving them where they lie. The
common case is that the transformation of all remembered models is the
same, so position any new model using that same transformation. If some
models have different saved transformations then it might be reasonable
to look just at the models with the same current transformation as the
new model -- if all those end up with the same transform then apply that
to the new model as well. If there is some real ambiguity (models with
the same current transform match the new model and then move to
different relative positions in the saved position) then obviously you
have to specify how to incorporate the new model in that saved
position. I won't have time to work on this for probably a few months.
Perhaps another Chimera developer will look at it.
As things currently work I think the only approach is quite painful.
You have to reset to a saved position then use the Model Panel / Match
button to align your new model with one of the existing models, then
reuse the "savepos" command with the original name to augment it. Ugh.
The matrixcopy command does the same think as the Match button and may
