A proof-of-concept / experiment revolving around
moving a DOM editing context-menu
element before its target, enabling
CSS selector ctxmenu[open]+*,
and JS no-query ctxmenu.nextSibling.
Pros and cons vs. window overlay,
unworkable with tables.
Also an attempt to do some template-less
dialog for code prompts.
An interest was to create some self-contained
JS/HTML snippet to inject in pages and
be able to select, modify and export selectively
parts, but in the end it cannot compete with the dev-tools.
