Will there be settings like Bitcrack in the future?
 -i, --in FILE
Read addresses from FILE, one address per line. If FILE is "-" then stdin is read

Yes, I'm thinking to add this. It will need an important refurbishment of the code however it goes in the same way as optimizing data transfer. So probably yes.

Code:
--keyspace KEYSPACE
    Specify the range of keys to search, where KEYSPACE is in the format,

START:END start at key START, end at key END
START:+COUNT start at key START and end at key START + COUNT
    :END start at key 1 and end at key END
:+COUNT start at key 1 and end at key 1 + COUNT

No (if I understand well the purpose of this option).
VanitySearch is a prefix finder in order to generate usable addresses, you can specifie a seed to generate a base key ,it is even recommended. That's all. The seed is then passed into a pbkdf2_hmac_sha512 in order to protect against seed search attack. If you don't specifie the seed, the basekey is generated using timestamps (in us) plus the date and also passed into the pbkdf2_hmac_sha512.
The result of the pbkdf2_hmac_sha512 is then passed into a SHA256 wich is use as the base key.
