ComScope v1.0.3

ComScope v1.0.3 - UI & Output Polish Release

Major Improvements

• Scroll While Paused - Scrollback navigation now works even when output is paused
• Pause Status Indicator - Status bar now shows [PAUSED] when pause mode is enabled
• Improved HEX+ASCII Readability - Cleaner HEX/ASCII column separation and better alignment
• Smoother Mouse Wheel Scrolling - Reduced scroll jump size for more controlled navigation

Bug Fixes

• Fixed potential issues with HEX / HEX+ASCII formatting on long or partial lines (safer buffer sizing)
• Fixed loss of trailing output in HEX modes by flushing any pending formatted data on exit
• Improved HEX+ASCII rendering correctness (newlines \r/\n are not shown as ASCII glyphs)

Performance / UX

• Better viewing experience in busy sessions by allowing history scrolling during pause
• Cleaner terminal output formatting for binary/structured device logs
