• Highlights, inspector, status bar, settings.

Workspace:

• Tabs, split panes, drag-and-drop.
• Side-by-side compare with highlights, sync scroll, diff navigation.

Analysis:

• Search HEX/text with progress, save results.
• Hashes (MD5, SHA, CRC), histogram with export.
• Inspector with offset, length, binary view, integer decoding, search/diff results.

Built-in terminal

Scriptable command line in the panel below the editor (active document pane). Disabled in comparison panes. Type help for the full reference.

Command	Description
goto	Jump to a byte offset
hex, bin, ascii	Dump bytes in different formats
sum, xor, avg, min, max	Byte math over ranges
len, count	Length and byte frequency
read	Read typed values at an offset (--le / --be)
find	Search hex or ASCII patterns
cmp	Compare two byte ranges
crc, hash	Checksums and digests
help ranges, help filters, help crc	Detailed syntax docs

Ranges support decimal and hex offsets, multiple segments, and sampling filters (--every, --skip, etc.).
