Is this operator== needed anymore? It seems like you've removed the call site.

Removed.

super-nit: while you're touching this, possible to use the full names
("Description", "Filename")? This abbreviation is a little unnecessary.

[lfg, 2017/05/25 21:34:42]

Done.

This member is removable.

[lfg, 2017/05/25 21:34:42]

This is still set in UpdatePluginList, since the plugin list depends on the main
frame's origin.
