- create a dedicated set of buttons for addition of tags and smartgroups
to make those actions more visible as well as getting rid of th need to
select a tag/smartgroup to create those (turns out to be quite confusing
for newcomers)
- move UI elements around, regroup {add,remove,edit} symbol buttons to
harmonize with other parts of QGIS; the elements' placement feels much
more natural now
Allows creation of an index on an attribute in a layer for faster
attribute based filtering
Support depends on the underlying data provider for the layer
These may represent additional layers such as layers which
are not included in the map layer registry, or paths to
layers which have not yet been loaded into QGIS.
literal defaults, and qgis expression defaults) and automatically
handle unique value constraints on layers
Add a new method QgsVectorLayerUtils::createFeature which returns
a new feature which includes all relevant defaults. Any fields
with unique value constraints will be guaranteed to have a value
which is unique for the field.
Currently only in use by the split feature tool.

Returns a new unique attribute value for a layer. For numeric
fields this is the max attribute value + 1, for strings we
attempt to create a unique value by append _1, _2, etc to either
a specified 'seed' value, or failing that to the end of the
value of that field from the first feature in the layer.
a substring from a vector data provider
Base implementation iterates through all features, but
providers can override with optimised versions. Native
implementations for postgres, spatialite and OGR included.
Within the attribute table, there is a new button to trigger actions
which are not based on individual features but instead on the whole layer.
Normally they will perform actions based on all features or the selection.
In addition to this, a lot of cleanup has been done.
- A new favorite grouping system was added, which the symbols list
widget defaults to
- The selected tag / smartgroup in the symbols list widget now
persists when switching layers (and across sessions)
- The symbols list widget will update the tag / smartgroup combo
box when users add / rename / remove categories
- Users can now directly tag, as well as add to favorites, symbols
while saving those to the style database
- To streamline style management, groups have been removed and
fully replaced by tags
- Tags have been integrated into the import/export user interface
