Would like to be able to push a file to a device (or group of devices) the same way you can run a script. Upload the file, and specify where it should land on the devices locally. Rather than having to upload a script to download the file and pushing the script.
The file transfer module at the device level I find is fairly unreliable for larger files, so if the above feature is added, if should do some type of file parting to make it is able to continue if the connection is dropped or is weak etc.
