A standalone web-based editor for MDropDX12 messages.ini files. Create and manage custom text messages displayed by the MDropDX12 music visualizer.
Single HTML file, no build step, no dependencies.
- 16 font slots — assign face, bold, italic, and color per slot
- 100 message slots — full property control (text, font, size, position, timing, color, growth, burn)
- Inline editing — click any cell in the message table to edit in place
- Batch operations — select multiple messages, then set font, size, timing, position, or clear text in bulk
- Paste import — paste a list of messages (one per line) with automatic assignment to random fonts, positions, sizes, timing, and effects
- Randomize — randomize fonts and effects on selected messages while preserving text
- Font picker — browse and search system fonts with live preview (requires Chromium + Local Font Access API)
- INI parse / serialize — open and save
messages.inifiles directly - Accessible layout — wrapping batch bar and responsive layout for 200% zoom
