I have never made a game mod, even if I am software developer.
Decided to make a filter of what colonist proficiencies you want in a building.
That way you won't have to kick a botanist from a mine until a geologist takes his place.
At least I can give it a try
The heaters should be able to cover the whole dome, have you adjusted the radius on the heaters so it cover more ?? Would mean it need more energy but your dome should be able to be protected by 2 heaters if a small dome ?
I had that last evening as well, but I lucked out since the meteor shower struck a couple tiles away from my dome's. It did discover some resources for me though.
@Panos Nice tip about the switches, sounds like a good idea ! I was wondering what they were for since not seen anyone using them, even on the Paradox stream as well (so far, just come to part 4 so far).
Sounds like a good little mod. While you at it, any idea if it is possible to have a colonist with right profession automatically pick their right work place ?? Find it a bit annoying when you have as an example 6 Engineering spots open, and 5 Engineers arriving but 2 of them decide to go and work elsewhere while you have a couple without/wrong profession taking the engineering spot. Then have to micro management so colonists is on the right place.

Is not just another building or a crop or a sponsor. Needs more work. 
a) Yes. Had to rely on the switches heavily. Also got a lot of tricks trying to combat my failures....
Things I learned the hard way, and are not covered by any youtuber, who plays on "easy" or "normal" difficulty....
Switches are paramount.
Create a simple network on pipes and power lines. Not a straight line from point to point, but having more than one route to the dome & tanks.
Split the production of water into unconnected segments. And each one connects to the dome. Same applies to Oxygen.
If something fails, only that small segment is affected, not whole network. The dome can work as the interconnecting hub moving the stuff around.
Air & Water pipes can go through buildings. That way you have just a small tiny segment of 1 pylon connecting 2 production/storage buildings. No need to go long lines over the power lines.
(same applies to the dome). Is waste of metal and prone to damage if something big hits he area.
Fuel production separate loop away from water loop. Can be placed anywhere. Better still get moistorizers to supply the fuel production, and when you get the upgrade adding 50% on the water production, build a tank.
That way if dust storm hits, the fuel production won't consume from reserves, but from any saved water.
Wind farms are waste of resources. Yes constant power but is only needed when you have colonists living. By that time there are other methods to maintain cheap power.
Solar power is working 2/3 of the day covering fully the two shiifts, so set accordingly even the unmanned units, works better.
On that also the trick to conserve power. If you have two farms, make one producing morning, the other at night.
Same applies when you build the machine part factory. Since you ain't going to fill up two shifts, more likely not even the first, turn the other off.
Flying drone network is for the lazy who want to burn resources at the start, when these are scarce. Two trucks are better, and allow you to move stuff around. When idling gather resources off the map.
Before you send off your rocket the first time from Mars back to Earth, make sure that you have allocated to the RC the maximum amount of drones, even those belonging to the rocket.
And protect those left behind by the rocket. they will be needed.
If you get the Fungal farm, build it. It doesn't take space in the dome, is built outside. That way you will have enough space for 2 apartments, 1 factory, on a third triangle groser, 2-3 parks and the restaurant (forgot it's name). That will leave you space to place an Electronics factory in the first dome also, or third apartment. Especially if you are in a good spot with 2 rare minerals, and 2 metal mines, 3 apartments are must, and go for the medical spire.
b) I was looking at the mod, I need quite a bit of Lua coding. I will do it though but it will take bit time to learn
c) Yeah heaters have sliders!!!! Just saw it after you said so. Thank you
Think I was around 60 Sols when 1 built my 2nd dome, or bit further, only have 2 Domes, 1 small and 1 medium and just passed 100 Sols. Went to take some screenies and then decided where I will have my 3rd dome. 
My research is a bit over 1,000, so next ship I think I bring as many scientists and geologists as I possible can get. 
Something to consider is that you can move a degree at a time and the difficult level changes, around the highest area, just moving one degree higher (45 North, 112 West) and the difficulty went down to 395%.
Yes, you will discover other means of getting power. Well, all depending on how they set up the discoveries you making, if it more then I found (which it might) then you might not. Hmm all I can say though is I have discovered another mean of getting energy, so I know it is there but can guarantee that you will find it. After all, the discoveries is all randomized.
