Well, I like it, but I have no control over how many videos show other than having the number of results shown: "small" or "large" - FYI, small seems to show 4 videos.
If I could choose the number of videos, and the number of columns to show them in then this would be a usable YouTube Channel video browser.
As it is, I would suggest it's only really usable if you have very few of your own videos, or you are happy showing videos based on search criteria, with little control over how many show.
I also found that the Video Width setting has no effect - they all seem to show at regular YouTube width.
Good, but no cigar.
