It lacks something to be 5 stars

Hi,

Thanks for the review. However, I would suggest contacting the support before reviewing any product. ??

About your concern it depends how you have added the search form. You can use any of three options Widget, PHP code and shortcode to display the search form and all have options to modify the button text, css class etc please see https://ps.w.org/wp-extended-search/assets/screenshot-3.png?rev=2436853

Moreover, you can modify the whole search form template as per you need https://wpes.secretsofgeeks.com/settings#search-form

I hope it helps!
