✨ **Portable YAML Bank Management Tool** - Easily manage your Borderlands 4 serial number bank!

🚀 Core functions

• **Paste and Import**: Supports original serial number (@U... format) or YAML block (slot_X: + serial:); can import .txt files
• **Display and Sorting**: Sortable list, supports weapons/equipment filters, annotated/unannotated filtering, substring search
• **Comment function**: Quickly edit comments, right-click/Ctrl+C to copy, display the comments of the selected item
• **Intelligent Deduplication**: Deduplicate by serial number, keep the annotated items first (or both sometimes keep the first one), display the removed duplicates
• **Export and Merge**: Export the current view (custom indentation); merge the complete base library into bank.yaml (does not overwrite existing content)
• **Customized indentation**: Control the indentation of slot_X: and sub-lines (serial, state_flags)
• **Other features**: title display sequence count; French and English bilingual switching; light and dark themes; optional automatic decryption function
