Thanks for the fast reply.

You're right, GM_config is just perfect.
Thank you again!

Just discovered GM_SuperValue, really great, maybe it'll be enough? But if you have other idea don't hesitate.

Hi everyone, I'm seeking your help, I'm looking for a way to make a user-friendly blocklist.

I know I could block some element by hard coding it in the script but I need it to be easy to use as possible so it must be done without editing directly the script and just by clicking on a button. So I think I'll need a way to store data permanently but relaying on local storage or cookie looks too unreliable to me so I have no idea how it's done in TM or GM.

If you know similar script or some idea to acheive that, I'll be grateful. Thank you in advance.
