Very glad you went and had this checked out.
Anyone with diabetes who develops new floaters should be checked out ASAP. I will see people over the weekend if that is their history. It is much easier to get some laser treatment in place before bleeding obscures the view too much. I prefer to catch these during regularly scheduled check-ups before they bleed.
Non-diabetics with new onset floaters should have the new floaters checked out as well. These are same day appointments regardless of how full the schedule may be. I still remember the trumpet player who decided to go to a gig and wait until the following morning to call me. His macula detached over night and he wound up with a bigger surgery (vitrectomy vs just a buckle) and a longer recovery with a greater chance of an incomplete recovery. Yes, most will have no problems but since only someone else can look at the insides of your eyes it is worth having it checked so you can enjoy driving your Porsches and other visually oriented hobbies.
