Oh, sorry what I mean is that I've got a widescreen-ish 1280x800 screen and when you add on the browser's address bar and tab area, a task bar, plus the ribbon, it makes it like I'm looking through a letter box.
EDIT: I just realised it's not as bad as it used to be; the header ribbon used to scroll with the page, reducing the viewport's height even further.
The top header only scrolls down the page with at least a browser window height of 900 pixels to avoid a "letterbox" feel with both a fixed header and footer.
If you resolution is 1440x900, you won't get the fixed header because your browser's toolbar taking up space would put you under the threshold of 900 pixels of viewable space. 950+ vertial pixels would probably be the crossover.
Here's another.... if I run Opera minimised and with width set so that the horiz scrollbar appears, the navigation dropdowns don't appear..
I think the UI button are grossly oversized, as are headers. Is this made for mobiles, now, because it's an ugly interface on a desktop, not business-like, but... oh, I don't know... just unpleasing.
And Opera does not work at all well with markdown.
"Do I have to install it??" Not to please me.
Actually, "if I run Opera minimised and with width set so that the horiz scrollbar appears, the navigation dropdowns don't appear.." applies to FF also.
Unpleasing... too much space is given over to items which could be smaller and still have utility. But I think my biggest bugbear is the code detection thingy, as of old. It's too... diligent.
There seems to be an issue with OPs making long headers, too - they distort the layout, instead of wrapping.
Change can beget more work than is bargained.
