Could anyone tell me, why I can't create Lightning Component Tab on my full sandbox on 16 enterprise edition?
I just can't see Lightning Component Tab related list in the Setup | Tabs section... So, After creating component I can't use it neither in Lightning Component Tab and in Lightning App Builder too (in the custom components section).
If you havent deployed your My Domain to users then you will not be able to see the Lightning Components related list under Setup > Create > Tabs. Until then you will see only Lightning Pages related list.
