I love WinSCP, the only request I would have is to add a method to prefer files with a size smaller than certain file size. Often I have a long download queue from a cluster, and from time to time I just want to upload a few very short files. Like 2 TB download in 200 files, and three short textfiles to upload. I then have to manually click "execute now" on each of these files, which is kind of annoying. It would be great if files of a certain size would automatically be put on top of the queue. Alternatively, for me it would also work if files which are to be uploaded would be preferred and would be transferred immediately. For the latter, maybe a simple checkbox would suffice?
