Hi it seems that tangling from an indirect buffer does not work. Is this by design or a bug? Would it be possible to make this possible? I am working a lot in indirect buffers (one subfolder R packages, another analysis of data, a third one results) and would very much like to tangle from them instead of having to go back to the actual buffer.
