Though you can't use drag and drop, you can use Chimera's File→Open dialog or "open" command to open additional files, so you don't necessarily have to revert to Mojave.

It has many of the same features (fitting, segmentation, etc.) and many advantages (better on large data, many usability improvements, and several entirely new features).
