Additionally, if you have a standard lock (i.e. not with a linear unlock), you can also "split" your lock.
Relock
Allows to relock a lock, whether it's withdrawable or not.
Note: A relock will charge the 0.35% fee on current unlocked token. This means you will not have a round number, or integer, in the new lock.
Transfer Ownership
Transfer the ownership of a lock from you to another wallet. There is no fee apart from the network transaction.
Increment Lock
Lock more token in this lock. Note that:
You cannot set a different date for the unlock
You can lock tokens to the lock of someone else, hence make sure this is what you want to do (check the gear icon color)
The 0.35% fee is taken from the total amount you wish to add to the lock, therefore it will not be an integer anymore.
Split Lock
Split a lock in 2 locks. No fee except the network fee. As an example: If you had 5 token in the lock, you can convert to 2 locks of 2 and 3 tokens (or 1 and 5, etc.).
Notes:
You can only split "Standard" lock, not "Linear" ones
You can only split a running lock, i.e. not withdrawable yet
You cannot change the ownership while splitting, though this can be done afterwards
