It would be great if u could say: flattr every .... minute when playing or flattr podcast addict every .... day(s).
Cause the new flattr system without klicking is producing much more klicks and if u flattr only once per playback (podcast) or month (Xavier) the klick value is quite smal.
Flattr have not been great to provide tools / apis to the developers until now.
Hopfully this will change

Flattr have built a new podcast funding system. Maybe integrate with that?
