- Improves the backup list display with chronological sorting, colored grouping for full/incremental backups, and dedicated time column. - Changes backup folder naming to a consistent dd-mm-yyyy_HH:MM:SS format. - Fixes bug where backup size was not displayed. - Adds detection for encrypted backup containers, showing them correctly in the list. - Hardens destination space check: - Considers extra space needed for compressed backups. - Disables start button if projected usage is > 95% or exceeds total disk space.
