Also... i need a tutorial about how i can mirror a map...
Usually i Copy/paste, but it ends non symmetrical
Here hopefully this will help. For quick mirroring ctrl+i and ctrl+l are your friends, you just need to plan ahead a little in your layout. Quick note my 3D view is in Flat.
I'm gonna use this
simple asymmetric box with a spawn point entity inside. In one of the 2D views, I use the top view,
select everything you want to mirror. Holding SHIFT we're going to
drag the geometry off adjacent to it, make sure it doesn't overlap. Letting go of the left mouse button will duplicate your stuff. While still in the 2D view
press CTRL+L, you'll notice in the top right that the room has mirrored itself.
Pressing CTRL+I will then flip it in the other direction, making this room more of a Z hallway.
If you want to see this on a bigger scale here's a
before and
after thing of just CTRL+I. This map isn't truthfully ready to be flipped I simply did this as an example. I use the same method I described but with more selected, hopefully this helped.
Thought I would make a video on my update process and progress on pl_sandsnake, so enjoy

I liked the insights you provided, doing it in a changelog is a good idea. Though you might want to speed it up a little bit, possibly have a plan to know what you're going to talk about and cut down the video from 12 minutes to say 6 or 7?
