It's only active in the vocab dictionary at the moment, but if you search for something, it'll pre-fetch the results for the other three dictionary tabs, and provide the numbers for you just above the results (こと is a good one that pulls up results for all 4). One-click takes you to said results!
Let me know if you see any issues with it, but I'll be expanding it to the other tabs soon.
Since the results are only showing in the vocab dict, I can't jump between them without having to go back to the vocab dict each time. But I suppose that'll be solved once it has been expanded onto the other tabs.
