I suggest to classify the items in the builder，

Because scrolling down is a little bit annoying

with items messing.

Sometime you want to add a certain reward

and you had a hard time searching the items you need.

Having filter instead of searcher is simpler in my opinion.

the "check" and "add" are totally different and they can't be messed.

Also I am new to modding and isn't familiar with those condition and script skill.

I don't even know how flags work lol.

Plz ignore my grammar mistakes.

I'm not too sure what you mean by this. Could you include some extra detail?

I think it is best to sort them out...like what paradox did to the focus tree.

...like what paradox did to focus tree.

...like what paradox did to focus tree.

by the way this is just a "quality of life" suggestion.

You should update modding tools first.

Especialy the idea&event modding.
