[chimerax-users] no conformation comparison category in ChimeraX1.5 and ChimeraX-daily

Hey Guys, I am new to ChimeraX and just trying to adapt from Pymol to ChimeraX. I am using a macbook pro (15-inch early 2018) running macOS Big Sur. I was trying to use the morph method of ChimeraX to record some clips for my publication. But I couldn't find the structure comparison tab from the tools dropdown list. I've tried the 1.5 and daily build version and I couldn't find this tab in both. Any suggestions? Thank you, Best, Jiang Xu
