Can we have zoom level indicator on changeset map to understand which zoom level we are in while reviewing in changeset-map?

Along dedicated buttons to jump into zoom levels for z12 and z16.

This is to understand on which zoom level a particular bad edit might render in. This helps in understanding severity of a bad edit.

👍 currently there is no sense of scale in changeset-map which makes it difficult to:

  • Estimate the size of features in an unknown area
  • Understand the visibility of a change at certain zoom levels

Having such information directly helps a reviewer analyzing a change in osmcha to be able to asses and tag the severity of a bad feature.

Possible ideas:

  • Have a toggle to show tile grids with x/y/z info
  • Display an overlay text like Zoom: 16.2 on the map
  • Keyboard shortcuts to jump to a specific zoom level: 1 = z2 World view, 2= z5 Country view etc..
