Question: Is there a way to enhance my Roundcube webmail experience with plugins and skins?

If you want to take your Roundcube webmail to the next level, RoundcubePlus is a good option. It's a collection of advanced features, plugins and skins that can improve productivity and the look of the interface. With the AI-Powered Email Composer, integration with cloud storage services like Dropbox and Google Drive and a mobile interface, it should work on whatever device you're using. RoundcubePlus supports Roundcube 1.5.x and 1.6.x, and you can install it yourself or use a cloud-based version depending on your needs and budget.

Another plugin worth a look is Ellie, an AI-powered email assistant that learns how you write and can generate responses based on the context of emails. It works as a browser extension for Chrome and Firefox and is available for Gmail and Fastmail, though other web-based email services are on the way. Ellie can save you time and boost productivity by automating email responses, so it's good for anyone who has to handle a lot of email.

If you're interested in AI-powered writing tools, Compose AI can be used to integrate with Google Docs and Gmail to help you write. It can suggest autocomplete text, rewrite sentences and adopt your own writing style. It's geared for people who write a lot, like copywriters and bloggers. The plugin is free to use, though premium features require a subscription.
