Dear ChimeraX Developers, This is Reza and I’m a computational chemist and protein designer. I’ve been a long time user of Chimera and now ChimeraX. Among many visualization programs that I have tried extensively including PyMOL, VMD, Maestro, ChimeraX has remained my favorite. I just wanted to take a moment and write this email just to say thank you for your amazing work. Even though it is free for academic users, this email is the least I should do after so many hours that I have enjoyed using it. The interface is great. The diverse set of features and modules are awesome. And the command line and scripting capabilities are so intuitive and easy to use. Can’t wait to see what comes next. Best Regards, Reza ChimeraX 1.10.1 on macOS Tahoe
