Add new selection tools that work across layers.

• Select by Click
• Select by Rectangle
• Select by Polygon (and freehand while mouse is pressed)
• Select by Freehand
• Select by Radius
• Add/Remove to/from selection when pressing Shift/Ctrl
• Select all features from all layers
• Invert all features
• Select by expression

One can also exclude some layers, that will not be used by the mutli selection tools (see Settings dialog)

Example: Multi selection with the polygon tool

• Selection color: affect icons, rubberband, and features
• Set active..: If enabled and the active layer has no selected feature, change the active layer to the first layer with at least one selected feature
• Replace default action: If True, replace the QGIS selection tool with the multilayer selection tools. Else, add the multilayer selection tools in their own toolbar
• Display settings action on toolbar
• Included Layers: list the vector layers in the current project. Unchecked layers will be ignored by the multilayer selection tools (useful for ignoring a vector basemap for instance).
  • If Exclude hidden layers is checked (default), the selection tools will not select or deselect any feature belonging to hidden layers (unchecked in the QGIS layer tree view)
  • If Always include active layer is checked (default), the active layer will not be ignored even if it is unchecked in the list.
