NB: I replied to this in the split off topic where it should be I guess.
Why not have a further section for file type, and grey out the resolution boxes if they are not relevant?
How about having one export dialogue with tabs for pixmap and vector export? Within those notebooks you'd select the exact filetype like png, jpg, tiff or eps, pdf, ps, ai... This seems logical and has the advantage of being able to have the dialogue opened all the time. I totally agree with bulia that having to go through the save dialogue all the time is plain crazy. Especially for web development the export dialogue as is is real nice.
I support this solution. In fact I suggested it a little earlier... but my post seemed too long to be read, sorry for that.
