v1.19 has enabled a work-in-progress feature for editing "datasheets", which are molecule databases + other field types, but necessarily constrained to tasks where the amount of data is small enough to fit within memory (think hundreds/thousands of molecules, not millions). The datasheet format has its own simple XML layout, but also interoperates with the ubiquitous SDF. For this version, there are undoubtedly lots of bugs and inadequacies, but they will be resolved with time.
