OK, we have a Sextante tool "points to line", though without option to sort by 
attribute.

Aihe: [JPP-Devel] Do we have a tool "create a linestring from ordered set of 
points"?

Hi,

I can do what I want in PostGIS with https://postgis.net/docs/ST_MakeLine.html 
but that is an extra step for my purpose that is to check if points are ordered 
correctly and if there are outliers. Natural order by feature ID would be 
enough for my immediate use case but a more universal tool could offer an 
option to sort point set by a selected attribute, that quite often is something 
related to time.
