Yes. The existing UI already supports tweaking the weights and re-generating. In the near term, I’d like research notebooks to allow even more powerful experiments with tweaking the cred.
Also, in the future we’ll support ‘heuristics’ which basically allow adding custom logic that rates or evaluates contributions. And, of course, people can create new plugins that incorporate new data sources.
Going even further afield: we could totally imagine different sub-communities creating their own cred and grain that are based on the shared cred. For example, we could make “documentation Grain” that is exchangeable with Grain in SourceCred, but represents contributions to or support of documentation efforts in particular.
