When adjusting wall thickness, make it possible to select in which direction the wall should expand
We have had serious issues with wall thickness in Sweet Home 3D:

First, the good: If you create an entire room from interior dimensions and then double-click the room to add walls, the walls are added, with default thickness, to the OUTSIDE of the room, without impacting the measured room size. Great.

However, if later I want to adjust wall thickness - for example increate it by 10cm - half of the increment (5cm) is put on the inside of the room and the other half (5cm) is put on the outside. Thus, the expanded wall thickness essentially "eats" into the established room dimensions, and the interior dimensions no longer fits the measurement as it is now 5cm shorter than before (and, if there is a neighbouring room, that one is 5cm shorter too).

I get that this can't be automated as SH3D has no idea in which direction to expand the wall, but it should be possible to add an option, when adjusting wall thickness, which could have three options: (A) Expand half on each side, (B) Expand into North/East, (C) Expand into South/West.

(North/South would be for walls going horizontally across the computer screen, East/West for the vertical ones. Maybe it could be phrased better, or even visualized on-screen to avoid confusion).

Ideally there should be something similar for shrinking walls, although I'm not sure what would be smartest there as you obviously don't want gaps between rooms...
