[Chimera-users] next/previous buttons suggestion

Hi, I like and frequently use the next/previous buttons (present in the daily builds) for sequential model display or activation. They are very useful for quickly comparing multiple 3D classes, or multiple aligned atomic models. One thing that would make this feature even more useful would be the capacity to lock display of a model - that is, temporarily remove it from the next/previous sequence. This would be useful, for example, when one wants to keep a single “reference” atomic model (or density map) displayed, but sequentially compare with multiple other maps/models. Would this be possible to add? Either as a command, or adding another checkbox that controls the lock/unlock status of the currently displayed model. Cheers Oli
