[Chimera-users] Include "perframe" command as action in Animation panel?

Hi Oliver,

  It would be nice to allow arbitrary commands to interpolate between key frames in the animation graphical user interface.  A small issue is that the vertical line indicating the the current time can be moved to any position between key frames — with a command interpolation it would be tricky to allow the code to interpolate just part way.  Also the commands usually specify the exact number of frames and if the key frames were moved to increase the time interval between two then the number of frames would need to be changed.  Maybe the command could be specified with a special character to indicate where the frame count should be plugged in.  I also like your idea of exporting the commands that will reproduce a movie.  I’ve added feature requests for these things for ChimeraX.

	Tom
