Del, the solution is in some of the new routers. Both the newest version of the 1617 and the MRC23EVSK have a round sub base plate which can be centered perfectly using the centering cone shown in the photo. This process will also perfectly center the guide bushing adaptor so if you guide off the sub base plate or a guide bushing there is no need to alter positions, just rout from where you are standing. No cord tangle this way. Something else you can do to reduce the twist up is to hang an extension cord from above your work table and plug into this. The cord will still twist but it wont try and fold back on itself like it would just running off to the side. Of course there is always the battery operated PC router, no cord period.
