Hi mate!
I am extremely sorry that your post wasn't allowed through. I don't have a damn clue why itch.io blocks some users from making comments/posts on this forum. Both your comment and post were 'pending' and waiting for my approval, but I was never notified about it nor is the 'pending posts' page something that pops out on the forum page. I need to contact itch.io about this, it isn't the first time and it is incredibly frustrating.
The feature you asked for is available since a few weeks now. You can enable 'Clickthrough' in the 'General' tab, or got to 'Hotkeys' tab and set the 'Toggle clickthrough' button so you can do it at will.
Again, I'm very sorry, I didn't see your posts.
