Experiences and suggestions
Here's a list of things I noticed that might you want to improve. Some maybe a little too specific, but that's up to you to decide.
-Exclude images/slots from exporting to atlas
I setup my projects to have the complete character in the background as a reference, but it is also exported to the atlas. This may be solved if the reference image can be set as a background image, but before exporting I now need to delete the reference image first.
-Fine grained control for positioning images
I would like to use arrow shortcut keys to position a slot image with little increments
-automatic slot selection for dragging does not always work, sometimes it's better to highlight the slot in the tree and drag
-additive blending does not seem to work
-clicking in an empty place in the dopesheet does not select the frame, you have to click in the bottom bar
-when there is no selection in the hierarchy, selecting a key in the dopesheet highlights it, but the UI won't show the values of that key properly
-I would like to be able to set bezier curves as preferred curve for every key
-I would like to see a value graph for animated values so I can see the result of the transition curve directly on the resulting values.
-More complect predefined key transitions (bounce etc.) For one of my animations I wanted an elastic bounce effect. I needed a number of keys to reach this.
-Masking of images (for instance an eye ball) In my current animations I could get away with an eye ball behind a body cutout, but I can imagine cases where there would be no room to move an image behind another one. In that case a fixed mask on the animated image would come in handy.

Exclude images/slots from exporting to atlas We could change "Selectable" to "Background" and then say we don't export backgrounds.
Fine grained control for positioning images Arrow keys do this for images in setup mode already, when translate tool is selected.
automatic slot selection for dragging does not always work Can you explain when this doesn't work?
additive blending does not seem to work It works in the editor. Not all runtimes support it yet.
clicking in an empty place in the dopesheet does not select the frame Correct. Click and drag in empty space is for box select, but we could make just click change the timeline position. Not sure it would be annoying.
when there is no selection in the hierarchy, selecting a key in the dopesheet highlights it, but the UI won't show the values of that key properly Clicking a key doesn't select the bone. Click the rotate/translate/scale/color label in the dopesheet to select the bone and appropriate tool.
I would like to be able to set bezier curves as preferred curve for every key This could be a global preference at some point. For now you'll have to select many keys and change to bezier.
I would like to see a value graph This would be nice, a lot of work though! We went with a simple graph for now as there is so much to do still.
More complex predefined key transitions (bounce etc.) This could be done, though I wonder if it would be useful to everyone.
Masking of images (for instance an eye ball) This would be nice, but would need to be supported in all runtimes.
Thanks for the feedback!

OK, sounds good.

Ah, how did I miss that.
Nate escribióautomatic slot selection for dragging does not always work Can you explain when this doesn't work?
The selection seems to be based on picking inside the bounding box of the attachment in a slot. Transparant pixels are ignored so with overlapping attachments the one on top is always selected even if you click in a transparent part. This often results in dragging of the wrong slot.
Nate escribióadditive blending does not seem to work It works in the editor. Not all runtimes support it yet.
Ah, I see. I need to first deselect to see the result of a different slot color. With standard blending you see the image change directly if you select a different color.

I don't think mouse clicking will collide with dragging. It confused me as novice user.

OK, but why not also select the bone?

Nice to have.

I agree.

Hey, we want to keep those Trello boards filled. ;-)

Thank you for developing Spine.

Oh, in the editor area? The image that is highlighted should be the one modified when you start dragging. Transparent pixels are not ignored. It uses image centers to determine which image to select when images overlap.
Ah, I see. I need to first deselect to see the result of a different slot color. With standard blending you see the image change directly if you select a different color.
Strange, I see slot color changes happen as I change them on the color dialog.

Will give it a try.

Don't want to smoke the users selection if they don't want it, which I presume sometimes you don't want it to change when you select keys.

Nooo, too much to do already! :p
OK, but why not also select the bone?
I have a better answer for this, actually. The bone is not auto selected when a key is clicked because it would change what is visible in the dopesheet. However, if you lock the dopesheet then clicking a key does indeed auto select the bone.
