Very useful. However, checkerboard background for transparency is bad for the images where transparency matters (think a video game sprite, where the background for the character is 100% transparency); it must be easily toggleable.

It’s great. Note that the keyboard shortcuts are not obvious, you should look at the “Keyboard shortcuts” pane in the settings dialog.
