Hiding and rearranging input options?

I recently purchased a template project from the asset store. It comes with several already named inputs, most of which I do not need for my project. Is there any way to hide so they won't be displayed to the user when the configuration window pops up (if I try to delete anything the project doesn't work anymore)? Also, is there a way to quickly rearrange the order that the inputs are displayed in without having to delete and recreate the array of inputs?
