Simply put, I saw that you have some form of crafting table upgrade for backpacks on the forge version which adds a separate crafting table in the UI rather than forcing you to sacrifice 9 backpack slots aka a whole row for the crafting module. This is genius so please add it to the fabric version of the mod if possible. Thanks.

It's already available on fabric, you can download it here: https://www.curseforge.com/minecraft/mc-mods/travelers-backpack-fabric/files/all?page=1&pageSize=20
