Manage files

№	Platform	What has been done	Why
1	Android	Create draft Android version that loads debug page	Research WebView to understand how it feels like, its limitations, and UX
2	Browser	Display files with accordion and tables	Simplify navigation and search for files
3		Implement copying, renaming, and deleting files	Remove the need to use CLI to create new pages
4		Add External button to open rendered page in a separate browser tab	See how the page looks like in real life outside PSKOV
5		Report missing or empty pskov.cfg	Helps you notice you specified the wrong path to a project
6	Node.js	Handle POST /delete	Let Browser part delete files
