I had at look at your plugin with interest since it looked very similar to my plugin: Hide Admin Notices.

I was surprised to see that your plugin works exactly the same as mine, in conception and functionality, because you have copied ALL of the source code (bar the PHP).

Whilst my plugin is published under GNU license (as all WP plugins), so you are entitled to copy it, it would be fair and honourable of you to add a comment with a credit to the original author (me) before the code that you have copied.

I hope that you will do the right thing and I wish you luck with your endeavours.

"You can see these notices at anytime simply by clicking the Show Notices button in the top right-hand corner."

There is nowhere a link or button to show the notices, that are successfully hidden – and yes, there are notices and yes, they are hidden.
But there is no button to show them.

Please fix this!

The Show Notices button in the top right corner does not appear.
