Hey! Thanks for your contribution!

We noticed that your plugin image is just a basic screenshot of a form field. To make your plugin stand out, we recommend improving the image by showcasing the plugin’s functionality more clearly. You can include the plugin name, a brief description, or an illustrative representation of what your plugin does rather than just a form field screenshot.

A good plugin image helps users understand its purpose at a glance and makes it more appealing. Let us know once you’ve made these improvements. Thanks!

Hey saade!

Is improving the plugin's image mandatory? I'm mainly doing it for the community, because I was asked to.

[Doriiaan]

I'm doing it now :)
