[interface] Item Type column (will show up on the right if you already have Scholar installed, but on the left for all new installations.), sortable.

[style] Better add/remove Creator buttons.
[fix] The sorting should not randomly switch the order of two items with the same sort value (eg, Barnes vs. Barnes).
[fix] The browser should not open with two sorted columns.
