For some reason i haven't had the need to do this before, mainly because i don't usually export gifs... but when creating an animation, there seems to be no way of exporting a .gif (or any other video format) at any canvas size other than the page/drawing size. That means I can't export it eg. twice as big, or half size. This seems like a fairly big omission for a vector graphics tool. Am i missing something?

If I use the standard "export..." menu option, I can save as a gif, and specify a size, but it only saves the first frame.

An alternative would be too select all objects from all frames at once, and then resize them all together... but i can't seem to select across multiple frames either (even when "display all" is selected)

Am I missing something for either of these options? Please tell me that I am!

It seems my only choice right now is to export as a series of PNGs and then use some other tool to create the gif. (which is annoying because I used the background and overlay frames, so I need to combine those as separate layers as well)
