Hi all. First-time post here, mentioning a couple issues. I hope the devs read this.

1)

Why doesn't setting a layer to Blending mode>whatever have the same results as painting on a layer using that same mode? (example: If you set a layer with a big white X painted on it to Linear Dodge, it should have the same effect as painting a big white X directly onto a flattened image, in Linear Dodge mode, right? Well, it doesn't. At all.)

Here's an example of an image in which I decided not to do a brightening effect over the text, because of the time it would waste (and layers it would add): <http://img292.imageshack.us/img292/6083/tempdl4.jpg> (on the top is a layer set to Linear Dodge mode, put over the text. On the bottom is the SAME THING, except painted directly onto a flattened image. Both should look the same, but they don't)

Whatever the reason for this (I'm sure it's a technical issue, not a design decision), SOMETHING should be done to get it fixed (even if it requires some kind of hacky emulation). I *desperately* need this working for what I do with layers. If I want to overlay a color-dodge effect over text, for instance, without having to Rasterize the text, guess what: I can't, unless I flatten the image. If I create a color-dodge layer over the text, it looks like a generic brighten. The only alternative is to duplicate the layers I want to affect, mash them all into one, THEN do it... which is a NIGHTMARE if I want to come back and adjust an underlying layer.

Filename copy.jpg

Why the word "copy"???? This drives me out of my skull. I save close to 100 images per month, and when I go to save, it's always defaulting to putting the word "copy" in the filename. How many people have EVER, EVER specifically wanted a file saved with the word COPY in it? -5,000. In fact, -every_user_that_has_ever_used_Photoshop, all irritated by this. If you MUST have this automation for somebody who actually wants this, make a checkbox for it or something in the save dialog.

My 2 cents, which weigh heavily in my pocket.

"...If you set a layer with a big white X painted on it to Linear Dodge, it should have the same effect as painting a big white X directly onto a flattened image, in Linear Dodge mode, right? Well, it doesn't. At all..."

Well, it DOES. Are you sure your brush and layer opacity settings match? Is the brush flow set to 100%?

The result of a Linear Dodge blend is a straight addition of substrate and layer (or brush) values. If the addition exceeds 255, the result is 255. Simplest of all the blends.

Yes, I'm fairly certain. It's been like this forever on my end (at least as long as I can remember on CS2 and CS3).
