Enhancement Proposal: Improved UI/UX for CouchDB

## Hello CouchDB Team 👋,

I've been a user of CouchDB for some time now, and while the functionality is top-notch, I've noticed that the current UI/UX could benefit from a refresh. I believe a modernized interface will not only enhance user experience but also make CouchDB more appealing to a broader audience.

## Proposed Improvements:

### Streamlined design
> Simplifying the **overall** design to create a more **streamlined** and **aesthetically** pleasing experience.

### Modern Typography and Icons:
> Updating **typography** and **icons** to reflect modern design **standards**, improving **readability** and **visual appeal**.

### Enhanced Color Scheme:

> Introducing a **modern** color scheme, possibly with the inclusion of a **dark mode** for improved user comfort.

### Dark Mode:

> Introducing a **dark mode** will provide users with a more comfortable viewing experience, especially during extended usage in **low-light environments**.

### Enhanced Sidebar:

> A redesigned sidebar can improve **navigation**. Clear **categories** and **icons** can make it more intuitive for users to find what they need quickly.

### Separate Logs and Stats Menu:

> Creating distinct sections for logs and statistics will allow users to efficiently monitor **interactions** with the database. This will be particularly useful for **troubleshooting errors** and **analyzing responses**.

### Collaboration Offer:
> As a **`web developer`**, I'd like to contribute to this initiative by providing a sample design for the proposed improvements. I believe a minimalist and functional design can elevate the overall user experience.

> If the **moderators** are open to it, I'm willing to create and share a sample design for the improved UI.

The issue does not name any files, tests, or entry points. First review the existing CouchDB UI and agree on a focused scope among the proposed redesign, typography, colors, dark mode, sidebar, and logs or stats menus; done would require an accepted design and corresponding implementation criteria.
