mia Haven't had any problems accessing the site. Occasionally while working, the next bill doesn't appear, but a refresh sorts that out. Once when a page was open for a little while (it's easy to get distracted with googling to find out more), it wouldn't save, and a "Request failed with status code 403" appeared, perhaps timed out.
I was surprised that all volumes at one point were complete for me, though I knew I hadn't done any work on many of them.
It would be nice if the move function could be controlled via mouse/touchpad rather than the arrows buttons, like the zoom. Generally everything functions very well, except tags, but that topic has been discussed above.
