I really like the new Create Entries page, but the fonts could be better. It looks like "Monospace" font family is currently used in the edit window, and this is not the best choice for international and non-latin alphabets, for example Ukrainian and some other languages which use Cyrillic script (абвгґдеєжзиіїй). This causes issues on Mac OS where Latin and Cyrillic fonts in Monospace have different weights, it makes the entered text look non-uniform in the edit window (but not in the resulting post because it doesn't use "Monospace" font in view mode). This issue can be easily fixed if we stop using "Monospace" in the Create Entries edit window, and use "Verdana,Helvetica,Arial,sans-serif" instead.
