How can I slide the scroll bar of a Panel?

and also the bloddy panel.

Error in Text Panel, turns to dripping red stuff

You’re right. I don’t know the answer either. GDI+ I think simply wasn’t designed to draw large amounts of text all in one go. GDI reserves small amounts of memory for caching objects needed during drawing, such as fonts, fills, pens and images. If one of those pools runs out, it’ll just stop working with an ‘out of memory’ error, even though you may well have gigabytes of memory left outside of those pools. The size of the pools depends on the Windows version btw. it’s not a constant.

Thank you @TomTom for your always valuable feedback.
I was using it for a comparison between 2 “similar” panels, sometimes I prefer to use a visual inspection, but you are right that long lists are not practical.

Anyway, is it possible to change value colours individually like this?

WISH: Colouring values in a GH panel?

Quick mockup of how I imagine this would work. [metacolouring] The main problem here is knowing what you need to name these metadata so that the panel interprets it correctly. Somewhere there will need to be a list of predefined names that Grasshopper understands, possible in the form of a categorised Value List object.
