[ShellShock]

Regarding the line-height I think the following is happening: my epubs have a line-height set only in the body class. On my Sony PRS-650 this line-height would be cascaded down properly to individual paragraphs, but on the Glo it is not, but is overriden by the line spacing option in the Glo's font options. For some reason the line spacing minimum value seems to be greater than 1.0em, more like 1.5em, so that is a problem - the minimum values needs to go lower.

But you are right, you can get the line-height you want by explicitly setting it in the paragraph class/style, which then overrides the line spacing in the Glo's font options, which is what I shall do in future. But still, the Glo's line spacing needs to allow smaller values.

In fact, I think there should be an option to turn off the Glo's styling, ideally individually, so it will only use the styles in the epub itself. Perhaps the only one I would use then would be font size, but I normally prefer to set that in the epub itself.
