Hi, Thanks for your report.
Regarding the first part of your report, ie. that pan no longer supports per-group threading: You are right, but that only constitutes a wishlist bug, since it is essentially a feature request. Regarding the second part, I am unable to reproduce with pan 0.112. Pane sizes are remembered across pan sessions. To sum, I am lowering the bug severity to wishlist, and forwarding the first part of your report upstream. -- Søren O. "Oh, bother" said the Borg, "we've assimilated Pooh".
