The not-quite-finished wkstats page is probably your best bet - go to the Items tab and select Wanikani, then you can play around with the configuration to get it to show you pretty much exactly what you want.
I’ve got mine set so the current lvl is at the top (with all lvls above hidden) and locked and burned items hidden. This lets you see what items are lined up for your upcoming lessons as well as which ones are working their way through the SRS.
