Woah! They've changed the journal writing page layout thingy! That probably happened ages ago and I never noticed...
...That aside...
So I've just moved a whole bunch of old deviations into scraps.
(What I would really like would be another category like scraps, called 'archive', where you could just move old stuff, or automatically send deviations over a certain age there. And then keep scraps as actual scraps - sketches and WIPs and suchlike.)
This is partly because I have too much stuff in my gallery, but mostly because of the new 'more from this artist' box, which keeps displaying thumbnails for old rubbish alongside all my new stuff.
