Feature request #13750
filter legend according to canvas extent AND scale visibility range for layers
|Pull Request or Patch supplied:||No||Resolution:|
it is complex to find sometimes what is the actually displayed layer when we have visibility on scale ranges applied, especially with raster basemaps that are made for a specific range, and displayed with others.
Having a visual indicator on layer (icon, color?) is a way. Having a filter based could also help cleaning up long legends. This would be helpful also for QGIS server use case.
New expressions improvements on legend filters could be used for that.
