Monitor preferences isn't fluid after 3rd monitor plugged in

[Daniel LaSalle]

I have just upgraded from dual monitors by adding one up now up to three.

Detecting the monitor went ok. However recalibration messed up my screen positions.

Another issue is that when attempting to recreate physical setup under "monitor preferences" isn't very friendly. Read: you need to battle with it.

By "battle with it" I mean that you cannot just choose any monitor and flip it over per it's physical position. In my case I was able to replicate my setup after having dragged the right-most monitor instead of the center one. As moving the center one brought hell in the interface.

By "hell in the interface" I mean that the flow of the monitors wasn't easy. It is impossible to simply drag and drop the monitor wherever but instead it will move down into some impossible position and REFUSE to go back up, or worst, to it's original place.

Before plugging in the 3rd monitor I had a full workspace displayed in the regular left/right format.

After plugging in my 3rd monitor that workspace had been separated and broken. So instead of dragging the mouse from the left monitor to the right one as regularly I had to access it from the left side.

Before plugging in this 3rd monitor both of my screens (the ones in red and blue colors) were close to another without any green space in between them.

Of course in order to reach the spawned desktop in between any of those monitors I need to drag the mouse quite a long road before it reaches as we can see from the amount of green spacing in between them.

Since I know some of you like to watch here is what it looks like when I screen captured from left to right.
