Option to view the entire content or the summary

First: Great Plugin!

Very nice would be an option to display the entire content or only the summary (number of characters / separators) according to the Grav configuration in site.yaml

summary:
enabled: true
format: short
size: 150
delimiter: ///

Unfortunately, I am a beginner and cannot adapt the plugin accordingly.

best regards

The issue names the Grav Feed Plugin and the site.yaml summary configuration; start by tracing where feed content is selected. Compare the full-content and summary cases against the enabled, format, size, and delimiter settings, with the work done when feeds can display either configured summaries or the entire content.
