Obviously I sometimes read without reading. Sorry, tomos!
A few years back we briefly talked about a program that among other features could offer to perform a number of processes automatically - like resizing any picture arriving a certain folder. I think that particular feature only included a (one) folder - and you need more folders - but hey, time has passed, and maybe it has been further developed - or of course not developed at all, I don't know, because I don't recall what program it was - but I think it had to do with photo editing.
But of course it would be better to have a tiny, targeted application from skwire, than a fat multithisandthatprogram for a single feature.
