Actually ... I think it probably looks awful because I don't think I have any of those themes available.

I think Sigil built using the official Qt download has limited options for what themes are going to work. There's only one shared library in the Official Qt 5.4.2's plugins/platformthemes directory-- and that's libgtk2.so. I have no real idea what the connection between a platformtheme plugin and themes actually IS, but I would think they would be connected.


As such, I'm not really sure there's much we can do. Those who have other themes available can try them. We could have an environment variable override to make it a little easier for users to experiment, but they're still going to need to know what they have available to them first. And in that case, they'd probably be able to modify the launch-script themselves anyway.
