I love your theme, works great for my site (www.kerbalspace.agency). Was just writing up a post and wanted it to be broken up into a section of pertinent information to display on the main page followed by a more detailed section to come after a Read More tag. But I also want to tell people what's in the section. I feel awkward putting a sentence at the end of the first section saying "Read on for more details about the flight data analysis" because in the actual article (when not viewed from the front page) the Read More link isn't there. So that made me think if there was a way to use the WP post Custom Fields to define a caption for the Read More button, so instead of just saying "Read the rest of this entry »" by default I could tell it to say "Read more on the Flight Data Analysis »" instead. Or anything else I want to specify.
I'm a programmer but not yet well-versed in PHP and coding stuff for WP themes. Just let me know if you think something like this would be possible to setup with your theme, and I'll figure out how to do it. Thanks!
