Not a new problem for me. it first did look it worked fine in sansar. But the current way you hit limitations.
It's very hard to do exact placement.
In blender you can move object very exact with cursor keys. (or wasdec)
It would be very helpfull when you place things like doors that need to be aligned pretty exact to with the cursor keys and pgup/down. As far i see this can only be done if you press extra key as example shift/alt or ctrl + navigation key.
Also the tool to move the object is not always in the place where you need to look with your camera. It can be to low or behind you. So in this cases you could move it with cursor keys to get it on the exact position.
Mouse is not exact enough for placement.
Move tool is not always inside the camera view.
