[Subtract tool not working as it should]

‘Subtract’ and ‘Combine’ both work as expected here. If you want to retain the smaller shape, you need to copy it before subtracting/combining. Alternatively, use the ‘Divide’ command and then subtract the smaller grey shape from the larger one.

Like this. ✔️

[Metric measurement please]

Hi, I'd like to only use the real metric units, everywhere. Subdivided by 10ths — see upper edge of wooden ruler. 
Publisher subdivides metric rulers by halves like you would do in your medieval unit of measurement — on the wooden ruler's lower edge.
Switching from mm to cm to m or zooming in shows the madness. A proper design application's ruler would go
0 - 1 - 2
0 - 0.1 - 0.2
0 - 0.01 - 0.02

When I say everywhere, I also mean font sizes. In the age of sharp printers and screens, I really don't care about standard lead letter sizes. Call me a peasant if you like.

[Flatten Transparency]

I miss this Illustrator-function.
Input: Overlapping shapes with different colors and blend modes.
Output: Cut out shapes for each intersected part affected by colors below, color equivalent in normal blend mode. (No rasterizing, no pixels.)
