I was sorting out my lists the other day and I noticed that as far as the PLAN TO WATCH list is concerned, it's quite boring not to be able to easily distinguish complete dramas from those that have yet to start. You need to open all the titles to check it out, or just have a really good memory. It would not hurt to have a few more columns to be able to filter by: in progress, finished airing, upcoming. Or add the UPCOMING tag next to the titles, like the ON AIR tag. In this way, by exclusion, we can also understand what are the dramas that still have to go on air. I know there are personal lists too, but it would be nice to use the featured ones.
EDIT: the main point of my suggestion is that different users around MDL point out the need to sort out their featured list with more filters. If you have similar ideas post it here.
