Clicking on reactions is slow
When clicking on a reaction edge, it takes very long to load the PubMed IDs. It also seems to be dependent on the number of PubMed IDs (takes even longer if a reaction is based on several 5+ PubMed IDs. When clicked once, it is fine.
Minor: a space is missing between the PubMed ID and [10] (from 10 on) in the left panel.
