I cannot reproduce your first issue (1st not showing Checking).
The ETA is always a problem. Pre-check means low "speed" and therefore a huge ETA.
Suppressing it would be better, but the difficulty is that the queue is not
in "pre-check" state, but only the top item and potentially the next one could
already be downloading.
Nevertheless, I'll see if it's feasible to at least suppress the ETA during check,
