I asked on the GitHub page for the mod "Screenshot to Clipboard" if they could add compatibility with EMI's feature of screenshotting recipes. When using the screenshot feature for recipes you'll most likely want to immediately send it, so having it on the clipboard would be great.
The developer of Screenshot to Clipboard responded with:
Could you ask the author of EMI to add events similar to the ones used for Fabrishot when a screenshot is taken and when the file is saved? This feature is somewhat outside the scope of this mod, but if the maintenance burden isn't too high (i.e. there's an API that will be reasonably stable across versions, like the one for Fabrishot) I'd consider implementing it. Alternatively I could expose an API for EMI to call to copy a screenshot when S2C is installed, if that would be preferred?
