Hi
Yes a very useful feature.
I especially find searching through military records cumbersome, as the "hint" hits a single page in a multi-page document all about the same individual. Voyage records, similarly, can also be a 'faff' to wade through to track back to a vessels name and port stops.
Should it perhaps be defaulted to enabled dependent on the screen resolution of the viewer and/or viewed record? (ie default enabled for military and vessel voyage records where it is more likely that you want to skip forwards and backwards)
I would observe, constructively, that when you click on a new "frame" to see - there is nothing telling you that the page is being updated. Perhaps there needs to be a "Loading..." sign somewhere to show that something is happening...
Best wishes,
James Usmar.
