This is a nice idea, but I think you could use a single tab, and instead have a ROW per item being requested.
I have 6x items in this picture and the GUI is slowly taking over the whole screen. https://imgur.com/a/CJ3t3L9

Each row would have the following :-
- item to craft
- number to keep in inventory
- Pause/Play button to enable/disable the row
- "Trash Bin" button to delete the row

Maybe some buttons to change the priority in the queue, move up / down.

Thk for tips. I use it for the next releases ;)

i try to make i think to write but that was very difficult :( .... is search a more simple way

the pause/play features is in standby....

The new features coming soon. Probably this week end.
