Meta issue - ideas, hacks, scratch-pad

[sigman78]

This is one meta issue to collect small ones (before deciding if they are worth to split or not)

• Supported languages cleanup do over. The list could be further trimmed down and keep it a single file.
• Move standalone static files into public folder. Notably robots.txt - otherwise it won't make it into dist
• Vector favicon?
• Add "parent-id" into db, when forking paste
• Deal with difference between <textarea> vs <code> line wrapping modes.
• Line wrapping in editor/preview
• Async highlighting?
• Mac Meta shortcuts on top of Windows
• 'Quote' duplicate method + UI
• MD type of documents 'Preview' render mode ?preview
• Same way as MD - 'Preview' mermaid diagrams
• (small) binary files support via in-browser UUE-like encode/decode (drop file, gets encoded text paste)
• Non-CF docker hosted version
• Modernized HLJS KW highlight rendering CSS Custom Highlight API or just migrate to prism.js
