Dear RBVI,

Sometimes I accidentally open more than 4 maps into UCSF Chimera session without changing the number of histogram that can be shown to some value higher than the default value of first 3 maps. UCSF Chimera places new histogram on the spot where the 1st map used to be, and the histogram order shown on Volume Viewer goes from

- 1st map
- 2nd map
- 3rd map

to

- 4th map
- 2nd map
- 3rd map
 
from top to bottom. I know that I can bring back the histogram of 1st map by clicking on Data drop-down menu, but it doesn't bring back the 1st map to the top slot.

Is there any way to manually re-sort the order of the histogram so that it would be in the order of their loading (or in the order of their model ID)?

Best,
Junha Song.
