Transfer and link short names (transfer_1, transfer_2, ...; link_1, link_2, ...) are created in-order as found first in log file A, then log file B, and so on. This means that if log file A has 10,000 transfers then it consumes nicknames transfer_1..transfer_10000. The first new transfer in log file B will be transfer_10001 despite the fact that it may have occurred before any of the transfers in log file A.
This is obvious in the Log data section as the transfers are shown in temporal order: transfer_10000 may be the first one in the section. This is confusing.
It is a bigger problem in the Link name index and Transfer name index sections where the links and transfers are shown in serial order. A response transfer may be in transfer_3 while the initiating transfer is in transfer_10001.
Showing these sections with the serial order also being the temporal order would be a big improvement.
