Ditto. I use systematic name prefixes throughout - for engineers, Thargoid stuff (crash sites & meta-alloys), Guardian sites, Mats traders, planets with raw materials, handy tech brokers and interstellar factors... I also try not to bookmark at a system level, but always use the relevant station/settlement/planet within the system, so e.g. if I want an engineer I can just take a look at the settlements list and they are all there in a meaningful order - E (Bubble engineers), OE (Ody bubble engineers), EC (Colonia engineers), OEC (you can guess). Bookmarking at the lower level also means I can one-shot-plot a route back to Colonia (Jacques) or Sag A (Explorer's Anchorage) if I get the urge
I try to keep my favourites list fairly trim - my home station & carrier, handy CG locations (temporarily), and where my AX ships are (since the fleet list scrolling in the Galaxy map broke a few updates back).
