thanks, yeah i do something similar myself. but it seems it must have been an obvious oversight that being able to select multiple images at once was left out.
in fact i cant think of any application i use (and i use alot) that doesnt let me make multiple selections of any items (files, images, etc) at the same time.

seeing as a new version of AW is on the horizon, i hope some of these smaller time saving updates will be made to make AW even more efficient.
