I installed foobar2000_0.8.3_special.exe (2.482.065 bytes) and copied foo_uie_albumlist.dll in the components directory. The dll is listed as loaded, but I cannot add it to the sidebar because it doesn't appear in the "panels" submenu when I right click the sidebar.
I fixed the problem by replacing foo_ui_columns.dll (which was an alpha version

) with version 0.1.2.
