I noticed that the tile structure option arranges the models logically when there are 5 or less models opened. When there are 6 or more, the arrangement is a little bit chaotic, the models are not placed sequentially. Could this option be improved so the sequence is more logical? Thank you very much. Chimera is great!! PS: I am used to work with EM models, I don't know if the previously described behaviour also applies to atomic coordinates models.
