Added sample groups to the File Manager for organized sample management. Added the Move function for assigning samples to groups or returning them to the main list. Added Back navigation to switch between groups and the main sample list. User sample selection now opens directly in the corresponding layer's group for faster workflow. Implemented automatic grouping based on sample name prefixes. Added missing sample indicator "(!)" to the select button when the sample is no longer found. Added three playback modes to the Shard generator: Granular, Oneshot, and Repeat. Some minor user interface improvements. Description updated. Also available as a PDF file on app site. Several minor bugs were fixed.
