Could you please add new keyboard shortcut for "Export settings to XMP" option? It could be "Ctrl + E" or "Ctrl + Shift + E" for instance. Both shortcuts currently are not used.
It's oddly, that so frequently used option still has no key shortcut. Personally I use it very often (cause I don't want to lose my edits in the middle of the process) and going to menu every time I want to save settings is a bit annoying as it takes time.
