• "client-server" feature (see client-server.md)
• preview's pattern is kept when changing file
• selected line in preview, interesting when removing the pattern (to see what's around a match)
• faster availability of huge files in preview
• search in preview now interrupted by key events (just like the trees)
• a content search in a tree is propagated as a regex in a preview on :panel_right (ctrl-right)
• syntax theme choice in conf.toml
• {line} in a verb execution pattern refers to the line number
