[Qgis-developer] [Processing] how to handle selections

[Bernhard Ströbl]

Hi all,
processing sports the "Save selected features" algorithm. However if in 
processing's options you untick "Use only selected features" the 
algorithm outputs _all_ features of the input layer. Although I know 
that processing works only on selections when the option is ticked IMHO 
the current behaviour is not intuitive: if an algorithm in its name (and 
help) claims to do something with the selected features it should do 
that _all the time_.
Opinions?

Background: I opened a PR [1] yesterday for an algorithm that works on 
selected features all the time (won't make sense otherwise) and would 
like processing to be consistent in that respect.

regards

Bernhard
