Yes i get updates for this program quite often.
You can actually use this program to open and view Gimp gradients, and brushes.
Pretty handy.
It is also an excellent Shellout addition to Gimp.

Is that some other software which you use with gimp? I know Rod had said it views the gradients and the brushes

It is actually a whole other graphic creation suite for Windows.
It is freeware but not free source.
It can read gimps gradient and brush files.As well as use Adobe filters effects (8bf's).

Sometimes if i want to see what a gradient file i downloaded for Gimp looks like i will open it in Chasey Draws viewer.
