Hey just a few suggestions here...
1] Since clicking on My DC no longer leads to a drop down menu so the playlist are accessible only through the videos page. I was thinking maybe it would be a good idea to add "My Playlist" to the My DC Menu that appears on the left along with the blogs, messages, dashboard etc. to make it more accessible.
2] Could you'll bring back the drop down menus it made things much easier to access with one click instead of 2-4 clicks. I think I read a while back that this was just a glitch but am not sure anymore.
3] Now maybe I am just getting picky but I always felt that a lot of good videos are not getting recognition by just being put in the Misc/Others category. I feel like videos like EPTPE, The Haj School, Poker Sense, Shuffle and Flow etc. deserve a category or categories of their own maybe something like General, Psychology and Tilt ( I have something similar setup as a playlist as a work around http://www.deucescracked.com/playlists/65281). Also maybe DC could have a game type for the Draw games and not have them lumped with the Misc/Others category.
Lastly I know MTR was working on improving the accessibility of the information in the videos to making climbing the mountain easier any updates on when we will see any of these changes on the site.
