Alabaster

I haven't found any import method either, aside from opening the document and copy/paste-ing it into the new one. It works without a hitch for me.

I would find it useful to be able to add text boxes or object that are visible off the white space, for instance, Being able to put a little circle or something to use as a horizon point would be great, as I currently use the corner of a window when zoomed to fit.
 
 

Sneak peak of the piece Im working on at the moment...It's got a tad complicated, but I have to report the software has not lagged, frozen or crashed once. So pleased with it, I had to finish a couple of projects in illustrator earlier and missed Affinity.

Yeah - got to help, then in the search box type "keyboard shortcuts".  That should give you the topic you need :)
 
Thanks,
Ash
