it seems that although new recipes are being created and added, it will prioritise vanilla then "non catalyst" recipes, would it be possible to change this to check for a catalyst first?

or even, possibly a filter on the extruder itself to specify what output you are wanting it to create, in which if the filter and recipe around it match it runs?

as seen here i have added a blue ice recipe to make the cobblestone generator make ice, but its only making cobble. i have also done this with a deepslate block below it to make deepslate renewable but that doesnt work either

Both options implemented.
Now the block has a filter for selecting the output.
Added priority for recipes with catalyst.

just a note that applying the filter does work, however it fails to render what is put in

Hi!
Right now I'm not handling priorities or sorting the recipes and that leads to the kind of lack of controll you mention.
I'll look to put a filter on the block.. I think it's a very Create way. However a sort mechanic or a defined/configurable priority would nice too.

Thanks for your suggestion.
