I forgot about your question and not sure if it got answered.
While in the PTW screen, click on the arrows to the right of the columns named Country, Year, Type, Episode, Score and Priority. Choose "Score", duh, lol.
If you don't already know, you can also make a drama different priority levels. That option is in the pop-up box when you add or score a drama. Go to "Advanced" on the left side menu. Then in the PTW screen you can click the "Priority" column to see which dramas are high/medium/low interest.
In the same pop-up box I can see about when I first watched a drama by selecting "History". It doesn't seem to add the rewatch timestamp though. And it doesn't give actual dates, which some members have asked admin to consider doing.
I can also click on "View Notes" when I want to find a new BL to watch. I add "BL" to the note section when I add a BL drama to my PTW list. For your completed dramas you can include things like "Cute!" "A Dud!" or "Sad Ending", who recommended the drama, where to watch the drama, etc...
Well, that's prob waaay more than you wanted or needed to know, lol.
