I'll bite, how do you organise your survey fleets?
Well, that was a bit tongue-in-cheek actually. Not really a specific "trick" with the Naval Organization tab (thought they're in there), but in more a general way to manage large scale surveying without micromanagement hell. Surveying (especially geo-surveying) is fiddly so I like to set things up so I don't have to issue a bunch of orders to lots of TGs; or have too many designs.
In my current game, I've got two designs: a jump-capable exploration cruiser that has both Geo/Grav Sensors (this is important). And a small commercial geosurvey craft. The exploration cruisers generally operate solo with 'Survey Nearest Survey' location orders. They've also got geosurvey sensors so they can check out interesting looking planets for ruins (with a sensor probe first), but generally leave the mass mineral survey tasks to the Geosurvey groups.
My geo groups consist of one of the EX cruisers to act as jump tender, plus 5-6 of the GEO ships.
Default orders are: 'Survey nearest body', and 'Follow higher fleet in system'. Using 'transit and divide ships' as the transit order into the target system, which passes the default orders down to the sub fleets. So each ship goes and surveys, and then when they're all done they gather around the EX cruiser again. Hit the 'assemble' button and they're off to the next system. Only have to touch them to move them to a new system, and I don't have to constantly fiddle with default orders. That's why it's important that the tender also has Geo sensors, so it can accept the same defaults as the GEO ships without event log spam. Now it doesn't have a parent fleet so it does complain about that default order triggering; which is your signal that they're wrapping up and need a new destination system.
Now if only 'assemble sub-fleets' was a conditional order it might be possible to arrange it to queue up several systems in a row. Even still, this method keeps things sane and I can mostly ignore surveying except for interesting results (and enemy contacts of course).
