It would be great to have a more descriptive name for the field group exports that ACF generates. As a developer for an agency that builds multiple sites I often copy groups between installs but the current naming scheme does not tell me where the export comes from.
Including the domain name or having an option to change this at run time would be awesome! I realize that I could easily rename the files myself after downloading but this seems like a simple enough request that I thought I would ask!
You can also rename them before saving them, but this depends on your browser settings. Whenever I download a file I get a file save window that asks me where I want to save it and I can also change the file name before saving.
