I say "minor" because it seems they would be fairly easy to change or apply, but I don't know what programming may be involved.

1) Timestamps in the Fleet Bank Log (seems they might be useful in some instances)
2) Ability to search by more in the Fleet Bank Log (I can search by tab name, item name and withdraw/Deposit, but attempting to search for a particular person's activity seems to be unavailable)
3) Ability for Fleet Officers to see when members have joined the fleet (good for those fleets with time requirements for promotion)

I would also add to the wishlist the ability to copy out of the log page such as implemented in the general STO chat window.

Not exactly Fleet related, but I know I use Mail to send things to fleet-mates quite a bit, so I guess tangentially it fits:

1) The ability to send more items at a time (don't need 50, but would like more than 5)
2) The ability to remove individual items form the mail rather than all or nothing.

As a fleet leader, the suggestions that Knight and Kalmyia have mentioned would help A LOT, especially for security reasons. The fleet log feature needs to have much more depth as well as many other current fleet features.

I also wanted to suggest that there shouldn't be any restricted number of sending out fleet mails as a fleet leader rank. I can only send one fleet mail per day and that counts for the whole account, not just one character. It's very limiting and I need to be able to communicate to the members when I need to.
