I once had a bug report, which stated a window was hard to see because it was partially blocked by another window. This was "fixed" by proposing moving one of the windows. Yeah people can somehow find a way to mess up anything.According to my experience with the average F95 user I doubt it
However I do believe a significant amount of people would be able to add 3 files as an update. If some people mess that up, then they can do the full download. There is no reason everybody should do that just because some (presumably a minority) can't figure it out. If we went by that standard, then computer mice would have one button because some people can't tell left from right. It's not like anybody ever tried making a mouse with just one button. That would be stupid.... oh wait.
