Do you think you could do two things to make your remarkable step-by-step guides even better:
• Having the ability to click in check-boxes for each step, it would also trigger a color-scheme (done / to be done) and a completion percentage display.
• Having the ability to display the various steps of the reversed order instructions to re-assemble the device, (it would feel much more helpful and safe to be able to follow the instructions displayed this way).
Be careful when putting the logic board back into place, you can easily overlook the small cable that fits at the top, otherwise you have the frustrating experience of having to remove all the screws again!
