Option to disable joining for hidden giveaways

Would be nice to have, I have to hide a lot of DLCs manually when I already own them. Not being able to accidentally enter one when I forget that I already own it would be nice

If disabling the button isn't an option I'd also take a more obvious indication that I hid that game/DLC, the current eye thingy is easy to miss, specially its absence.

A more intuitive design would to make that clearer on the Enter Giveaway button, like changing its color.

For ESGST users there's the Hidden Game's Enter Button Disabler.

Maybe CG can add this so for example when you own the game, the enter button is replaced with a previously owned button that you cannot click. In the above case mentioned by the OP, the enter button can be replaced with a hidden game/dlc button so you cannot enter it.

EDIT: looks like at46 has an option already available to us .

I hide every game I am not interested in and I always have to look for the missing eye symbol to know if a game is hidden when going through trains. I don't mind if the button still works to enter, but it would be nice if the button changed to a different color and said something about the game being on my list of hidden games.

I agree, it would be better to disable the "Enter giveaway" button or at least change its color for all hidden giveaways.

Bumb, again saw this issue specially with some bundled games from a bit ago...
