[Related Pages] Edit score_threshold via admin panel

is there a reason, why i can't change the score_threshold within the admin backend (blueprint)? all other values are available, but not the threshold.
(Unfortunately, not every admin can edit the file on the ftp-server.)

I can probably change this for my own setup, but I guess that it would be gone, when the plugin is updated, right?

thanks

If you need a customized plugin, create an inherited one and make there you're changes. You can use the devtools plugin for this.
Than you are certain that any changes won't be lost when the plugin gets an update.
