Hi Sergej,
thanks, but I think we won't build such a feature because we'd need to add another extra security/token-mechanism for multiple files making the whole software more complex and maybe slower. If you want to share multiple files we recommend to create a top level folder and use the "Share Link" function to allow others to browse and download the files they want without the need to login with an user account.
Nevertheless we plan a "Download folder zipped", so you'll be able to download a complete folder including all files and subfolders.
Sorry for that, but we hope the "workarounds" fits your use cases.
Best regards
Thomas
