Hi, as explained in #26085, on discord here and on the top of the repo home page here. We are currently in a period of "quality releases" where only refactor or fix PRs are permitted unless you have prior approval for another PR type. This is commonly referred to as a feature freeze.

As such, this PR is going to be closed. You are welcome to revisit the idea once the freeze has been lifted, but we encourage all contributors to get stuck in with fixes for items on the issue list!

I get the impression that this has not been properly tested
Here's a small review of what should be done first of all, add a if(isnull(value)) return check after input where it doesn't exist, secondly replace if(value) ... and if(!value) return with the aforementioned isnull().

Since tgui inputs return null if the player decides to close the window or click Cancel
I hope you don't repeat my fate with a bunch of follow up PRs on fix checks
