i like it

Keep this extension perpetually. Very good.

I hate it

doesn't load the page, i opened the extension, went off, played a game for an hour, came back and was confused by a blank tab, only to realize, IT WAS THE EXTENSION PAGE. so...yeah, it doesn't work.

This is a great extension to make your own theme. I would give it five stars if it had some more customizing features like making the menu/toolbar transparent for custom images. I would also give it 5 stars if this very annoying issue didn't occur where a tiny bit of line from the custom image shows up under the toolbar. https://i.imgur.com/1XdWroq.png

I hoped that this would enable me to fix an issue running in Ubuntu whereby the window maximise/minimise buttons are rendered in white lines which means you can't use a light background for the background colour (as then you can't see the buttons). But it does not seem to offer that.
