2 Features I want from Flattr

Flattr is a great leap forward in economics for the digital media.
It suites very well to - lets say - more temporary content, where new posts and contents are delivered on a frequent level, where you consume a thing more or less once and go forward.

But it does not scale propperly, when it comes to more static content. E.g. a piece of Software, a tutorial or a text which you use & consume on a frequent basic. Flattring it only once seems to me unfair, regarding the proportion of work put into it.

2 features would improve this situations:

a.) A possibility to "reflattr" something. The factor should be visible on the content I flattr.

b.) A subscription, so I will flattr a thing every month. Choosing a period 3/6/12 month subscription would be helpfull.
