18) You can upgrade a single facility at a time on a planet that has lots of the same facility. Find a planet with just one obselete facility built. Add the Upgrade Facility X item to the build queue. Click on Fill Queue, then Save the queue with an appropriate name by clicking on Add Type. Now, go to the previous planet. Use the Fill Queue button to add the single facility upgrade order. You can naturally have "Upgrade 2 X" or "Upgrade 3 X" fill queues by finding planets with 2 or 3 facilities to upgrade, respectively. Using this method, you can upgrade large Groups of facilities in small batches, thus allowing some to be upgraded immediately and begin functioning sooner than it would take for all to be upgraded at once.

19) You can use the hotkey ctrl + t to manually add a minefield marker to a sector, and ctrl + r to remove one. These can be used to mark certain sectors, such as damaging warp points, as no-fly zones. Your ships will avoid the sectors marked as minefields, trying to find a safer route.

20) Your exploration ships do not have to stop when entering an unexplored system. You can order them to "move to" a random sector in the system, such as the far side or center, after the "warp" order. The ship will merrily continue on it's way.
