So here's a feature i have wanted every now and then but could never really describe it The gradient tool has the great transparency feature, but it only works one way
Rei created a plugin that replicated this feature in a way, but it had an 'Inverse' feature
This would be an immense feature if it was baked into the gradient tool no? Of course there are other ways to achieve this (soft eraser, blurring an outline, vignette plugins, blend modes etc) but built in it would have fewer limitations on its use (not having to be in the centre, allows usage of other gradients, friendly with huge canvases)
