Thank you very much!
Few thing that I would suggest is an ability to add and easily remove several Userid, and not just one, and have not just playlists there but also uploaded videos, favorites and such. Also, it appears the maximum number of elements in a list is 25 - both playlists and videos in the playlist. Granted, beyond that it is getting harder to organize them, but they should still be there.
A few concerns:
If you were to add a user with no playlists and then go their videos page, channel crashes. If you add a userid that has a space in it, channel not only crashes almost immediately, but also is inaccessible later on - the only fix is to remove it and add again.
And, out of curiosity, where do you pool the data for "most..." and "top..." videos? A quick search does not result in videos mentioned. Tollywood category is a bit too specific (though, the only one with more than 25 videos per category listed), and 1080p is a bit useless as there is no sorting of any kind and very very limited.
