The program will crash when it tries to open xyz file with ~ 100000 atoms. Just segfault without exceptions.

There is no error processing when some file is imported as cube formated file. So the app will crash.

Does not run due to a missing library.
How was this AppImage generated?

qppcad: error while loading shared libraries: libQt5Charts.so.5: cannot open shared object file: No such file or directory

Are you going to realize export a scene with molecules to some 3d application such as blender, 3dMax or some other?

The menu item Tools->Generic tools->Structure similarity cause segfault when any xyz file is imported.

There is any way to set custom white color?
