These changes look good.

You might want to look at the Unpopular trait as well as the popular. The Measured, for example, have an Unpopular penalty that is so large that planets with a single tourism improvement don't get any tourism income. You have to build two or more tourism improvements (Import/Export Center, Paxton's Emporium, Port of Call, etc) on the same planet before you can overcome the Unpopular penalty and even start to get any tourism income.

Very nice update. Thank you! 

In my current game (started on 3.9 with all DLCs) I'm playing as The Measured. On one planet where I have Paxton's Emporium and Port of Call, I see each one of those contributing 1.2% (the extra .2% is because The Measured are aquatic), and Unpopular(1) subtracting 1.8%, yielding a net of +0.6%.

I think you've missed something, which I think is an error. The Basic Railgun has a kinetic attack of 1 and requires thulium as a resource. However, the Superior Railgun has a kinetic attack of 2 but requires no special resource. Perhaps you got them mixed up? I think it makes more sense to have the Superior Railgun require thulium as a resource.

It's been this way for sometime.  Several versions ago.  The custom race I use has the maximum unpopular trait and it results in it having to build more than three tourism improvements on one planet in order to gain tourist income.  I think this is a pretty good system because there should be consequences for choosing the unpopular trait and it goes without saying that being unpopular would reduce one's tourism income.

I found a small problem with this:

It works perfectly under normal conditions.  I found a star system with 3 planets to colonize.  I managed to colonize all 3 before the shipyard was built.  When it was built, all 3 were automatically connected to it.  Before this change I had to remember, maybe too many turns later, to manually connect the other planets to the shipyard.  Very irritating.  This way is much better and much appreciated.

The small problem was in another star system where I colonized one of the 2 planets and built a shipyard for it.  The other planet required extreme colonization, which I didn't have.  Another race eventually colonized it despite my strong influence in the system.  A number of turns later the planet flipped to me.

The small problem was that it didn't automatically connect to the shipyard.  I waited two more turns to see if it took a turn or two, but it never connected.  It was definitely in the green zone.

It would be nice if whatever was done to make colonized planets automatically connect could be done for flipped planets.

I like all the other changes also.  I'm having  to adjust to the planet build queue being moved and space rockets being moved, but I am adjusting.  I prefer the way they are over the way they were.

I found a trade bug.  I don't know if it's new, but AI civs will sell the farm for a working hyperspace gate in your territory.  I had the idea to give someone else a hypergate so they would connect it to their network and the trade value maxed out.  They will literally give every starbase, tech, ship, resource, and coin they have.  No colonies at least!  Haha.

The space gate trick works well though, not sure if intended.  I just build a circle of them by my primary staging point, give them away to other Civs and they hook them to their network givimg me access to the whole map.

Well crap. I'm sorry to hear that!  There's no real way around that I'm afraid.  What size map are you playing on?

Yes

okay thanks for the post i got it

All their planets, except their home world become class zero planets. You get their home world.

I propose it get tweaked so on surrender part of the planets and HW go to you on surrender and the others go rogue.

The percentage would vary depending on relations of the two.

The rogue ones would take time and resources to conquer/flip. In effect slowing you down.
