Can the current zoom level (0 to 20) be displayed somewhere in JOSM’s User Interface?
I know there is the scale in the upper left corner, but zoom level would be handy when writing/manipulating mapcss files with lines like…
node|z17[setting("shrink_nodes")] { symbol-size: 4; }
…to see if the mapcss works as intended at the given zoom level (here: 17).
PS: I already created a table which shows me that scale 50m means level 18, 100m means level 17 and so on. But this is a bit cumbersome.
PPS: maperitive for instance shows the zoom level in its status bar.
