No, TIM can't currently do that and offhand I can't think of an easy way to tie that into how TIM already works. It would probably be easiest to just write that as a separate script, for which you could certainly look at TIM for examples of how to scan inventories and how to display things on LCDs. If I find some time eventually I may do that, but it probably won't be soon, so if you (or anyone) wants to take a shot at it sooner I'll be happy to give suggestions if you get stuck.

Thanks for the reply taleden. I've got some ideas as pointed out in the reddit post. It makes sense that it would have to be a proximity thing as blocks aren't really "attached to" others from the perspective of the grid. It could also be that MMaster's LCD status script would be a better fit for this feature if you two don't want to overlap too much :)

If you'd like to give it a try yourself, as a starting point I'd suggest finding the spots in TIM where it uses the "panelSpan" structure in ParseQuotaPanels() and WriteTableToPanel(). Those sections involve reading the orientation of the first panel so that TIM can look through the grid below and to the right of it and identify the other nearby panels that will be part of the spanned display. In your case you'd want to do something similar, except that you'll use that orientation to identify the block behind the LCD, which would be the block it appears to be attached to. Then you can look at TIM's inventory scanning code for how to read the contents of that block (if any), which you can then display on your LCD.

ahh great idea! Thanks for the tip

I read through this and I may have a solution to your question, someone already did this script:
