I am glad to see that some blocks were updated to allow placement on the ground like these


But is there a technical reason that makes impossible the placement on the ground of blocks like these:

or the most famous:

The last one is used in many tech maps, in competition maps, I think it would be cool not to be forced to blockmix these. It would reduce the amount of requests like "I want an ingame blockmixer!". In the end, I would prefer an increase in placement possibilities of existing blocks rather than new blocks.
The simplest thing I also would like to see in a future update would be the possibility to create the blue concrete ground without the inelegant white roof.

It is sometimes really boring to try and hide this roof, by placing it as high as possible when it doesnt fit in the existing scenery... Why not put this blue ground in the same category as grass, water, and dirt ? I mean, it is already a ground type.
Lastly, it would reaaaaaally make sense to turn the placement type of inclined blocks into road-like placement.
It may be a bit hard to imagine, it could be a transparent inclined grid where the mapper can drag roads. On this grid, the Y axis would correspond to the "blue" blocks, and the X axis would correspond to the "yellow" blocks.
Advantages:
- unified mapping tree. Originally, inclined blocks are the same as flat blocks, the only difference is the angle with the ground. It would make more sense to be able to change the angle of mapping rather than expanding the mapping tree. That could give something like:

- being able to cross inclined roads. Because nadeo created a separated tree for inclined blocks, they couldnt make a comprehensive list of blocks. It lacks all the crossings like T or +
- easier, more intuitive mapping imo
Ask for more details or if i'm unclear
