Hello,
Both Logos 6 (6.0a SR-5 on OS X) and the Logos iPad app seem to use fake small caps in, for example, for the ‘ORD’ in a fully captialized ‘LORD’. Here is an example of the problem from the desktop application:

The ‘ORD’ in LORD here is being drawn with normal upper case letters at a reduced font size. As a consequence, the letter strokes are incongruously narrow and weedy compared to the other letters. The proper OpenType small-caps alternative glyphs should be being used in this context.
I know this seems like a minor thing, and it is, but the Logos software generally seems to care about correct typography, and this particular problem always causes me to double-take and is an unwanted distraction.
Since I’m on the topic of typography, I’ll repeat the request for a left-justified text option on the iOS app. Forcing full justification is distinctly unhelpful for readability, particularly with narrow columns.
Many thanks from an otherwise generally happy customer!
