It would be nice to export your Tvh settings/channels to a file through the webui (maybe splitting them to channels, settings, network, user ...).

At the moment you have to copy the user folder manually (not doable for a average user with 0 shell experience) - also this folder is not compatible if you change for example between Debian and OpenELEC or every other distribution which isn't following the Debian way for saving the user files.

Another advantage would be a better backward compatibility for the future.
If you ever decide to rewrite the way the settings are stored at disk, the user folder backup is kind of useless (up/downgrade).

To import the backup through the webui wouldn't care about the actually folder structure at disk or how they actually saved (db, xml ... ).

And finally lets adapt the single best feature of VDR, simple shareable channels + settings (sharing vdr channels.conf is quit common).
