Bought Studio Pro yesterday. Played with it for the rest of the day. Impressive!
Of course, I immediately have suggestions for the next minor version. Which is not surprising, because I have been requesting these same things since version 2.
1. Please, please, please, support multiple styluses. Multitouch is the latest fashion, but I don't use it. Painter gets it right: it memorizes which tool was picked last with each unique Wacom stylus tip, and switches to it when I use that stylus. Wacom driver actually transmits unique stylus IDs with its data packets; you just need to look at them. I am reduced to using one tool at a time instead of flipping five without stopping to click at palettes, here!
2. Please, please, please support stylus tilt and bearing. Pencil and airbrush already do; why do the flat brush and the palette knife ignore the bearing? They always rotate to be perpendicular to the direction of the stroke, even though they *begin* aligned to the stylus bearing. I might be doing something wrong here, but I cannot find any setting to make them follow the stylus instead of the stroke. This seriously reduces the expressive power of both. You can do so much more with a flat brush than drag it along the canvas; you can stroke with the narrow edge, or make angles. AR3 brush still only drags along, and produces unseemly artifacts at the beginning of the stroke as it snaps to the direction of the stroke from the stylus bearing. It can be made a configurable option if need be, but I view it as an essential requirement.
3. Some way to quickly convert a selection into a stencil, and a stencil into a layer. Right now, editing stencils (masks) is still quite a hassle.
4. A way to make the underlying layers' bump map another layer's paper texture. Right now, if I put some paint on the canvas and then use some chalk on a layer above it, the chalk reacts to the default paper texture, and it'd be much better if it reacted to the ridges and bumps of the paint under it. That would allow effects like pencils on gessoed board, and other neat things. The current way is rather boring.
5. A flat watercolor brush!!! The only thing we have right now is a rather narrow round one. No way to make really nice flat washes.
6. A way to control the spread of the brush. Right now, the flat brush reacts a bit strangely to pressure: it starts too narrow and spreads too much.
7. A spattery airbrush.
8. How about controlling the bristle quality of the brushes? From a smooth, even nylon to coarse pig bristle, to a worn, uneven brush? I've used some real-life specimens of the latter to produce excellent grass, foliage and fur textures. OK, going out on a limb here...
Otherwise - terrific work there, team! Well worth the wait and well worth the money.
