I want to say thanks to Ekuah first for this great script. I use it all the time since I discovered it.
I have discovered a problem wich might not even be due to your script but to SE itself, but since you or someone here has for sure run into it, maybe we can collaborate and make a table for everyone to use.

The problem is, that the Filter option doesn't always work and the reason seems to be, that internally some ressources have different names than the ones displayed.
Silicon Wafers and Magnesium powder for example can't be filtered for with those names. We could use "Silicon" or "Magnesium" but that would include the ores as well, which one might not want. If you want to filter for "Silicon Wafers" you'll have to filter for "Silicon Ingots" for the script to find it. Similarily "Magnesium Powder" is found by filtering for "Magnesium Ingot".

So I'll write my findings here and encourage everyone who found diverging names to add them here. If you find, that an item you filtered for does not display but you could not find out, what to filter for, write it here, too - maybe someone found out and can help.

So my findings so far:

Ressource --> Working Filter Words
~~~~~~~~~~~~~~~~~~~~~~~~~~~
Silicon Wafer --> Silicon Ingot
Magnesium Powder --> Magnesium Ingot
Gravel --> Stone Ingot
