Well, when you click on anything with line data in calibre's reports tool, which so far means Style Rules, you get sent to the line itself.
Everything Reports on files, obviously there is no line data, and word/character counts don't link to every time they are used...
I suspect any hypothetical Links Report pane would emulate the Style Rules.
I would prefer the Reports tool to be optionally dockable, rather than having its own editor and previewer. But maybe that is just me.
(I can do hourly reports.

Nothing new as yet. It is 6 AM there though.)
