Option to bulk manage zites and automaticaly delete them after some time

Hello,

ISSUE:
When i want to free some zeronet disk space, it can be good to have option to bulk delete zites that i have not PINned/favorited and that was not visited by me for X months.

PROPOSAL:
The "..." menu next to ZeroHello logo may contain new item "Manage sites" and it will allow filtering and sorting the sites and applying bulk actions on them. Example when i want to stop hosting some redundant sites, i will be able to open this page and quickly filter out sites that
- i have not visited for more than example 365 days
- that have more than 10 peers
- that are more than 20 MB in size including optional files.
- that belongs to a certain (custom defined by me) category
- that are not in my favorites
- that contain some phrase inside its name or description

Then i can apply bulk action on filtered sites:
- delete them now / or with certain delay
- unpin optional files of these sites
- download all optional files
- export sites addresses
- tag them or move them into certain category

The "Manage Sites" may also contain other configurable options related to sites, example option to automaticaly delete newly added sites if it is not visited by me for X days while site must not be in category Favorites, MySites and MyCustomCategory.
