[Qgis-developer] New color ramp widget: suggestions

[Howard, Stephen]

I tried to request the following feature enhancement some time ago but
don't know if it ever successfully got entered into the system (the
suggestions website is very confusing).

for Singleband Pseudocolor:  after classifying a continuous image (say
NDVI) into numerous classes (10's to 100's), allow the user to select MORE
than one class at time for color assignment (i.e. Click to select initial
class, then shift <or control> click to select additional classes, assign
color to all selected classes).

Thanks for consideration of this request.
