currently no way to create new File when using SCP. I have to use Cyberduck at the same time to make up that.
Yeah you are right, but it's inconvenient to drag local file into built-in SFTP browser especially when you expand Royal to the whole screen mode in Mac.
We'll definitely look into this for the next major release.
It's true that there's currently no way to create new files from within Royal TSX. If you however switch your connection to use the SFTP protocol, you get a local and remote file browser. Then, you can create a file using TextEdit for instance, save it locally and drag the file to your remote file browser within Royal TSX to upload it.
