As presented in other bug reports Connect is limited to 100 entries in a playlist.
I suggest to do a simple increase to 1000, or even just 500 to at least help most users.
The reason I do this suggestion is that the other ideas suggests to remove the limit completely which might be impossible.
SO to follow an "Agile" way of developing software I suggest that the developers know discuss with the users alternative solutions instead of just trying to ignore the issue,
if that happens then really the "right team" is working with the issue.
