Hello the posibility of extruding walls would be really great.

What I mean by this is, you have a new square outside of the current perimiter of the building that you would like to pull out of the wall, you have to create 4 new points in the wall. What would be neat would be some sort of tool to just make two points and pull those out of the wall. The posibility of making this multiple times would be great too. Another neat possibility for this could be to make it possible to make the extrusions without clicking, but by telling the width and depth of the extrustion and then the distance between the extrusions like in the other copying tools.

Make something like "Extrude from Wall" and then you can select a depth, how far the thing should stick out of the wall and then every other klick onto the wall you can finish the tool and between every two of the klicks the wall gets 4 new points like in the screenshot below.

It would also be good for rooms to fill the extrusion seen in the picture. This would also be great to be possible to do simultaniously for multiple rooms at the same time.

I know this might be a niece request, but it would also be great to more easily make a lot more detail to models by more easily make repeated square patterns in the walls.

Interestingly removing such an extrusion by shoving it back into the wall works as expected and removes the corner points. Edit: No it doesn't you just select both points when dragging them. If you delete them they get weird, but there are two inside of each other...
