I've recently found that VT300+ standard contains ability to show pictures and ever video. Corresponding output mode named Sixel.

Supporting such mode may allow rewrite of addons like conemu-thumbnail in more standard-conforming way.

I understood if you tag this FR as "pr needed".

Is not possible until ConEmu internals would be completely rewritten.
I'll have this in mind.
