[Suggestion] make that "remove space" doesn't consider locked tracks.
i falled on this issue (very nasty) when making a videos with background music or voices. after placing the soundtrack (videos needs to placed "in time" with music) is nearly impossible to remove the space created by spacer tool... probably the automatic space remover need to "exclude" the locked tracks.
also the spacer tool is unable to reduce space (it can only add space)
