For those that are transferring their FM files from iPad to Mac via iTunes when you click the "Save As" button you get a dialog that is titled "Open". Also the confirm button is labelled "Open". I know that you are selecting a directory and one could argue that you are opening the directory but I rhink the majority of users would expect the labels to read "Save". To make matters worse when you click the "Add To" button the dialog title and the confirm button also read "Open". I have been caught out a couple of times where I thought I was saving a file to the Mac but in fact I was adding a file from the Mac and thus eraseing the original file on the iPad.
The only place that I could find to submit this to FileMaker was as a feature request for FMGO iPad and FMGO iPhone but I think the issue is probably in iTunes. Perhaps FileMaker have no control of this but it is an issue none the less.
