Things get put into Hijack mostly because I find them useful on my player, and/or significant numbers of others want them.

Breakout is there simply because it is cool, and has existed since v2 of Hijack (v1 had Pong instead).

But I do like the idea of removing all the stuff that needn't be there, specifically everything that I do NOT use on my player:

-- audio overlay
-- bass/treble adjust
-- EXEC, EXEC_ONCE
-- XML for the web interface
-- audio mute support
-- RDS enhancements
-- /proc/empeg_display.{raw,png}

These could save me a fair bit of buffer memory, and I have NEVER needed any of them.

Cheers
