FR: smart cleaning

[ggrrll]

Hi,

I know this is probably not in the top priority but it would be nice to have a tool that help cleaning (permanently delete) the trash faster and more effectively

• The first thing I can think is to actually plot the distribution of the email sizes, so that one can for instance understand if its storage is mostly busy with few large emails, or many small ones
• Then, one can think a sort of recommendation system that suggests with email to delete (like notifications from web services, etc...)

@ owners : what do you think?

happy to contribute, especially on the data analytics part
