Two edge transparency?

[Acorn]

Just to give more options. My weapon of choice is to add a linear transparency, then double click to add more nodes and adjust the transparency of each node.

0% in the middle, 20 for the next 2 outwards and 100% at the ends:

This has been my weapon of choice after it years to uncover that you could add nodes and apply different transparency levels. You use the Tab key to move along nodes and the Arrow keys to reposition a node; a Tab click when the range bar is selected does something different altogether.
