All due respects to engineers I am always suspicious of an aircraft that has just come out of maintenance.
And so you should be. If you are not asking what work has been carried out and expecting the unexpected you are not doing your job.
This however will not be on a list that you can simply work your way through!
Any work an engineer carries out stays with that aircraft. Pilots simply fly it and walk away job done. Flight data recorders, Voice recorders, QAR's etc. are changing this.
Flight deck video monitoring will be with us soon I'm sure.
A cheap and simple iphone app. could record everything pilots do/say. Probably be on every car dashboard first though.
