I would like the ability to choose the size of my canvas. When making diffuse maps it is suggested to use sizes like 2048 x 2048, 1024 x 1024 and so on. I would also like to have a level of some sort, like the one in photoshop and illustrator. The rulers on the top and side would be nice but not a need, but the level line you can pull out of them would be awesome! In addition to the texture creation, I would like to be able to import an image of a UV layout and keep it in the back ground, this would really help me paint my maps.

And the ability to zoom in twice as much as we can now would be pretty flippin' epic.

You can actually choose the size of your canvas(File->New[use the second New])

What do you mean by level? If I understand you correctly you want to be able to add a line, but I cant see a reason wyh.

For images in the background: open your desired png with BI then add a new layer and paint on it ;D tada

Higher zoom levels are confirmed(http://forum.bleank.com/viewtopic.php?f=29&t=49)
