The table saw is always connected to my dust collector with a couple pieces of 4” flex hose and some 4” sewer and drain PVC pipe and a homemade blast gate. The port on the table saw is at the rear of the cabinet and this particular area of the shop sees the least amount of foot traffic so I have no problem just leaving the ducting on the floor. I also always have a few other cords on the floor here. I see this as the same principle as walking onto a porch. You know the steps are there so you pick up your feet. I know the pipe is there so I pick up my feet. Not a trip hazard in my opinion.
Google is probably the first place where most people would start searching for woodworking plans, but often the top results can be a mix of articles and how-to pieces that just aren’t detailed enough. Sometimes they’ll link to the plans (like we try to here at Lifehacker), but other times, they’re just showing off a cool project. There are better, more precise ways of finding what you’re looking for.
