Is this user script allowed? (I made)

So I coded this tampermonkey user script to show labels on squares when you are playing on Chess.com. This only just adds a little bit of extra rendering, not anything that uses any kind of engine.

Is it legal/safe if I publish it to Greasyfork.org as an user script? I can provide the source code if needed.

Yet it's private to me. In chess.com's fair playing & cheating article I do not find anything mentioning user scripts.

Video here:

Changing visual elements is allowed.

Thank you for the quick response.

I coded another user script, which is just gonna let me type moves instead of using mouse. For example, I would double-press shift then type any move : `e2e4` and it plays it for me without me having to use my mouse. I could also type resign/draw/rematch/abort.

What this user script does is only to simulate clicks and reduce having to move mouse, if its not compulsory or I am just tired. Is it allowed?

That's very likely a risky choice and could potentially get your account flagged. You might open a ticket with Support directly using the option in the menu and ask

Thank you for telling that, I will be opening a support ticket to confirm the allowance of this script.

Is this really a better way to move pieces? Typing seems like more work.
