You do not even seem to have a publicly available repository for me to be able to contribute. Could you maybe fix it sometime soon?

There will be eventually as the site will be used as a blog, the number of posts will keep increasing overtime. That is the concern I had.

However, with the “Activate experimental autocomplete inputs” ticked, the user can now just write the name of the translation post without having to search through the a large number of posts/custom posts in the future.

Hello realloc,

I tried it again with the fresh install of wordpress and it works fine now. Somehow something could have gotten corrupt in the process.

I do have one issue though.

The dropdown menu showing the posts, would it be showing ALL the posts? This could get very messy if the site has a lot of posts. Any way to somehow limit it?
(Do let me know if this is an already solved issue because this is offtopic)

Hello Dennis,

Checked the screen options, the Translation metabox checkbox doesnt appear there. It does appear in the normal post box.

Should I have added something extra in this segment of code?

'supports'            => array(
			'title', 'editor', 'author', 'thumbnail',
			'excerpt','custom-fields', 'trackbacks', 'comments',
			'revisions', 'page-attributes', 'post-formats'
			)

Do I need to reinstall the plugin after making a custom post type maybe?
