The advanced search function should be in mywatchlist so that I can filter my own watchlist and select which drama to watch next.

1- Sometimes what happens we forget after putting drama in our list for a long time without watching a single episode or after watching a few episodes than when we try to remember why we have added this drama in our watchlist What was it that made us choose it for our watchlist? But we can't remember!
2- Sometimes we feel that we should watch dramas related to certain genre / tag / episode / length / actor / etc.

If that thing is in our own watchlist then we don't need to search the complete MDL.
