I don't know about the 787 but Airbus (A330 at least) had a little storage area for the gear pins and their flags, perspex door allowed both pilots to screw their heads around and see them when the checklist called for "gear pins and covers" There were 3 slots so pilots could see them all individually when fitted as designed. More often than not the engineers would just wrap them together and force the wad into the box and so needed to be sorted by the pilots.
Never forgot to bring the gear up but........ I thought it would not be possible to forget to put it down as the slippery twin I was flying could not be slowed to approach speeds without gear.....wrong!
