Hiding and showing stencils:
F6 is useful for hiding and showing stencils but it is no use if you have two or more stencils and only some are active. F6 will show all the stencils you have hidden. Can F6 change so that it shows and hides active stencils only.
Using the mouse or tablet to invert a stencil can sometimes result in accidentally moving the position of the stencil. When you rely on the inverted stencil to be in exactly the same position this is annoying. Even better would be a short cut to invert the palette.
Pressing F brings up the stencil palette. It remembers which category was selected except if you have the active panel selected. Can the palette be set to remember the active category. Can the mouse wheel be used to scroll the palette instead of the image? Can the palette also remember where it was between sessions. Restarting ArtRage resets its position.
As mentioned elsewhere, it would be useful to be able to increase the opacity of the stencil. If you use one stencil on top of another it is difficult to see what you are doing.
Grouping and locking:
I am finding it extremely useful to use two or more stencils together. The option to either merge or group them would be useful. I would also like to lock a stencils position so that it doesn't move.
Stencils as a stamp:
I would like to use a stencil as a stamp.
Grabbing and moving stencils:
Sometimes this can be tricky as it relies on an opaque area. If the stencil is sufficiently light it can be difficult grabbing it. Particularly noticeable on textures.
That's it for now!
