Script that tells you if the Kanji/radical you are on right now is new and brings progress

There’s the ultimate timeline which marks which up-coming reviews contain progress items*, also which those items are, as well as when burns are coming up. It’s different from what you asked for, but it’s a very helpful script I find. ^^

*strictly speaking, it marks current level items, so that includes vocab which doesn’t help leveling. But you can see the type of items on the timeline or check the details of an upcoming review, so you’ll know when those important kanji and radicals are due for review.
