Ability to Save Generated QR Picture Preview to Disk

[D-Maxwell]

As things currently stand, if such an ability even exists, it is certainly not clearly available.
The share flyout does not seem to offer any file manager entries, nor one to simply copy the image.
A download or save button would be appreciated.

Please use "Share" function and export the image to Google drive or somewhere else at this moment.

I will consider implementing your suggestion in the future.
