The view mode chosen by the user via the three icons on the upper right ("Full view", "Collapsed view" or "Small view") should be remembered.
If a user prefers to view one board collapsed he surely wants it to
a) actually stay collapsed when reloading the page
(which is not the case currently) and
b) probably also wants other board to be shown collapsed
(which is not the case either)
Therefore the chosen view mode should be remembered, similar as to how the CollapsibleNav state of the Vector extension is remembered.
