The Selective color adjustment is great, and I have enjoyed using it. However, in PS I was able to use it to make a saturation map. Details are here:

Though not exactly a deal killer, it would be nice to have a similar function in AP. Apart from anything else, it was a very useful teaching tool. Using it I can show students the saturation values of their paintings. 

 

 

EDIT:

 

I have just found a way to create a saturation map in AP. 

1)  Make a black to white Gradient Map adjustment.

2)  Using an HSL Shift adjustment, desaturate the result.

3)  Using curves (or Brightness / Contrast), lighten the result by around 100%

 

This will result in a pretty good saturation map. Apart from anything else, it can be used to mask a HSL Shift adjustment, to make a saturation contrast adjustment.

 

Which... brings me to another feature request: a curves adjustment for Saturation. This would be very useful, and not something that Photoshop is ever likely to have.

The Vignette filter is fine, but could be improved a lot. Currently, it emulates a optical photographic vignette. However, if I ever use one, I like to apply the darkening selectively to objects depending upon their lightness value. This takes its aesthetic cue from the way that a vista is constructed in a classical landscape painting (vistas are aesthetically related to vignettes). It is possible to do this in AP by applying the vignette filter to a white layer, then setting the blend mode of that layer to Multiply, then playing with the 'Blend Option' values (PS's blend if layer style values).

 

Additionally, a lightening of the centre can be applied. This can be done with a bit of color dodging (first a black layer, then set to Colour Dodge, then paint in gently some white).

 

My point is that all of this can be wrapped into one dialogue box.

Finally, it would be nice to have the option to have a PS style undo/redo. Though I prefer AP's way of handling many things over PS's, the way that PS's undo command Z worked, offered the ability to quickly compare the file with and without the most recent edit.
