INTERACTIVE NESTED SQUARIFIED TREEMAP • Scans real local and mounted directories using POSIX os.scandir and displays nested labeled folder frames wrapping colored file sub-blocks. • Double-click any folder block to zoom smoothly into its subtree; click the breadcrumb zoom trail or Back/Forward/Up buttons to navigate. • Single-click or hover any block for real logical size, allocated disk blocks, share percentage, modification timestamp, and child breakdown.

LIVE QUERY FILTER & TAG COLOR RULES • Filter the scanned tree in real time with expressions such as .log, >10MB, <7d, -.tmp, or tag:1, recomputing matching subtree totals live. • Customize four color highlight rules (Tag 1..4) or assign manual tags directly to files and folders, plus toggle free-space block overlay.

DRIVES PANEL, LAYOUT CONFIG & EXPORTS • Inspect real mounted filesystems from /proc/mounts and os.statvfs, customize nesting depth, minimum block size, and color palettes, and export CSV breakdowns, vector SVG treemaps, or PNG snapshots.
