Hi Eric, I see. For ease of windows management, I have most of my tools docked. However, resizing the monolithic window often results in changes to the sizes of tool/button panels as ChimeraX maintains their relative proportions. I was wondering if I could put together a set of alias-ed presets that would resize and arrange these elements to match the common viewport sizes I tend to use, e.g. to pair better with different monitor setups, or for ease of returning to a set state having resized away for whatever reason. I've just been tweaking my presets for (old) COOT and was inspired to see if I could do the same with my ChimeraX setup. No worries if no such mechanism exists. I can well appreciate the complexity involved in refactoring. Cheers, Yang
