I dont see the problem. I modded many games and usually it was the same as in il-2 1946: place a folder at a specific location and sometimes edit one or more textfiles.
That is true if you are just going to install a mod from a available link Istvan, download, install the folder, add the necessary text entries, that is the experience of guys who just want to play with the mods that have already been created for them.

In creating that mod itself things can actually get rather complex and very frustrating which is why most mods here are made by groups of individuals rather than individually.
Let us look at jet war for instance, at the upper end of the complexity ladder are the guys like Mike and Western who actually have to do the java coding to make everything function correctly in the simulation, I am sure you would agree that is a world away from just dropping in a folder and adding a text line.
To make those jets work requires countless hours of coding, 3D work, texturing and testing but Joe Bloggs like me can just unzip all that hard work, dump the package into the SAS folder and add what the team reccommends in the form of text entries and any relevant mods needed to make it work.
So to the figures that Geezer allowed me to use, at the upper end is the complexity of creating the 3D model and mapping and texturing, not to mention the conversion of those meshes into a format I can use.
I am at the intermediate or lower end of the scale shall we say and I use that work that has most likely taken a long time to complete and within a few hours depending on whether it is a single item or not I can then convert it and extract to a mesh before putting it together in a folder with all the necessary parts to make it function.
Following testing we then get to your scenario, it is uploaded and Joe Bloggs adds it to his install, hopefully correctly and it works, happy days.
Now Geezer as we now know is a software engineer so he will be able to do all that himself from start to finish as do the likes of Western and Dreamk but the cost in time and effort is incalculable.
So you can see why I say the simulator can and is in some ways very complicated yet in others not so.
Hence you then need to make that decision as to whether you just want to play or mod, if you want to mod then some things are simpler than others irrespective of the ability you might have and you need to decide where you want to fit within the big picture and how much time you can give.
Anyway, my throat is dry from all that talking and I am going to retire to the fridge and liberate a cold beer.

Bye the way, was that grain Silo okay, did it work for you?
Take care.
Wishing you all the very best, Pete.
