v1.9.1
IMPROVEMENTS:
- gui: accessibility. The colour-only device/cartridge status dots are
hidden from screen readers (their meaning is in the adjacent text), the
status line is a live region so connect/disconnect is announced, the
per-operation progress bar and result line are labelled, and the action
buttons gain access-key mnemonics (Alt+R read ROM, Alt+W write ROM,
etc.). Long auto-dump/-write/patch paths get a hover tooltip with the
full value.
