How to design your own tooltips?

Is there any info around how to create your own tooltips of a patch or type? The blogpost is not very informative about this…

We’ve deliberately not talked about this yet because we’re still finetuning. If you can’t wait for the official announcement, have a look at VL.OpenCV\VL.OpenCV.HDE.vl to see how it is done.

thanks, that helped!
