Feature request: gray out the Next button until the following card is loaded

[SnuggleCovenant]

I was going through secureblue's yafti on a low spec, low internet pc and it froze when it called to install flatpaks so i tried to unfreeze it by clicking next again and it jumped to the end once my pc caught up to the workload.

Graying out the Next button on click, then only reactivating it once the next screen is fully loaded would help communicate that the click on the next button was registered and is processing.
