Quirks of simultaneous play in 1.30

OK, now intercepting enemy fleets is hard enough but refit/ mothball /scrap has me completely confused.

From what i can see, you can refit multiple vessels in a turn as long as the is an INACTIVE shipyard in the same sector. This appears to work as long as your ships aren't in a fleet. I've managed to refit 10 ships in one sector but then seem only to refit 1 ship in a different sector when i ask for 10 refits there.... ????????
You can only mothball one ship per sector per turn ?
You can only scrap one ship per sector per turn?

This coupled with the fact that there's NO INDICATION of which ships you have flagged for refit / scrap / mothball is infuriating.

Anybody have words of wisdom to shed some light on the subject?
