Recently has been added the possibility to group the features using an input field, my problem is that it only groups these features if the chosen input field's values are strictly sequential : if a feature B is between two sequences of the feature A then those 2 sequences become 2 different polygons instead of one (A:1/2/3, B:3/4/5, A:6/7/8 instead of A:1/2/3/6/7/8).

Please install version 0.2.2 of the plugin and see if it does what you
need. It allows you to sort the points by the grouping attribute. You'll
find it in the plugin installer.
