In addition to current blur filter I request to add zoom and radial blur to the blur filter list in Krita, zoom and radial blur help achieving some specific effects while painting, Gimp has zoom and radial option in motion blur dialog, how ever I suggest having them separate, for visibility Reproducible: Always
Now we only need to find time to implement it :-)
WISHGROUP: Larger Usability Fixes
As I said on g+ group I too like to have this filter...
G'MIC does have a radial and angular blur which I think are very close to these two functions. While it might be quicker to access these filters in the main Krita main menu, I am not sure how high of a priority it is since it is in G'MIC already.
