First, thanks for the hard work on this program. Very well done.
I'm using it to capture periodic screenshots in automatic mode. I think a couple new features would make this even better than it already is:
1) allow "repeat until stopped", rather than limited to a set number of captures. would like it to just keep running without ever stopping unless I manually stop it.
2) add an optional feature to delete intermediate captures that are identical to current capture. that is, once a capture is made, it could compare it to the previous capture file, and if the files are the same (or even could have a tolerance where they are the same within some % deviation), it automatically deletes the previous file.
