• Fun with setting Paging Options! 🎉

  We have added this fantastic new feature called pagination_page_options in two areas - our helpful README.md and trusty config/filament-email.php. Now, you get more control to set your page options, which, guess what, makes navigating through the sea of information a cakewalk! Cool, isn't it? 🍰

• Jazzing Up our Table Method 🎷

  We've rolled up our sleeves to upgrade our table() method in EmailResource.php. We've introduced a new method call paginationPageOptions(). This unique feature fetches wonderful page options for your tables directly from the configurations, or default options if not available. Voilà, easier table handling directly at your fingertips! 👏🤩
