Update preset feature settings in yml files and README

Simplified preset settings in 'preset_features.yml' and 'preset_usage.yml' files by combining several lines into one. These changes enhance the readability and maintainability of the code. Additionally, alignments and comments in 'preset_features.yml' and README file were adjusted for consistency and better readability.
