Hi Kovid,
I'm trying the updated beta
Edit: OS X Mavericks.
I've noticed I got a lot of warnings in the terminal...
Code:
2013-12-02 13:14:30.913 calibre-debug[756:507] CoreText performance note: Client called CTFontCreateWithName() using name "Liberation Serif" and got font with PostScript name "LiberationSerif". For best performance, only use PostScript names when calling this API.
There's lots of them, for Serif and Mono, I then used the Preferences and set 'Courier New' font, when next run I still get a lot of warnings for Liberation and a few for Courier.
Doesn't actually affect the epub editing though.
A couple of other things...
I know it's probably difficult, but... if there are any embedded fonts, could they get 'picked up' for correct displaying in the preview pane.
N.B. Found that if I click the 'Embed referenced fonts' in toolbar (window/dialog says 'No embeddable fonts found'), then close the file's tab and re-open it - they get displayed correctly - so it may just be me doing something incorrectly.
When double-clicking on an image in the browser pane, instead of displaying the 'not-editable' warning, could you show a preview window with the image.
Would allow easier checking of images to get the correct filename for insertion in html.
