I vote for something like to put this information overlayed in the view, at the bottom right corner, probably by moving the current Z mm too.

[alranel]

The current unit is layers. Each step of the slider is a discrete layer, not an arbitrary Z in mm. The label below the slider shows the current layer's Z.
Layer numbers are not very meaningful, because support material can have interlaced layers and objects in the same print can use different layer heights.

Rather than just talking about the implementation, can you please focus on the test case and discuss why are you actually asking for such change? It's very unlikely that we do something if you don't share why you are proposing it.

As I said in #3022, this information (the current layer number) is less useful than you would think once the assumption that all extrusions on the same Z belong to the same layer is invalid.

That assumption is invalid.

So you will need to explain more comprehensively what you want to do and why you want to do it. Preferably with pictures.

Closing for now. @efa please add the requested information and I will reopen.

I do need the layer number for my colorchange script that uses layer number....
I cant understant why this kind of feature used in all other softwares is missing in here .... Really ...
You may be find this useless but it is a must have feature for me...

script used:
{REPLACE "; layer" "M117 Layer"}
{REPLACE " Z = " " Z="}
{REPLACE "\nM117 Layer x, Z=" "\nM600\nM117 Layer x, Z="}

i need to know the layer number to replace fhe "x" so i can keep printing in dual colors with a single extruder.... and i cant find it anywhere
example? sure, see the pic ;)

Use the [layer_num] variable in post-layer gcode to add your markers (or before). This is numerical and should be what you expect.
