instead of

==========

allow the user to add whatever text they want to show up as a header there. This would be a great place to have your blog title as ascii art.

### Feature Request: Allow Custom ASCII Art as Header

**Summary**

Currently, the header for the application is predefined and looks like this:

```
==========
== smol ==
==========

```
This feature request proposes allowing users to add their own custom ASCII art or text as the header. This would enable greater personalization, such as using a blog title, a unique design, or other creative text.

---
**Use Case**

Users could provide their own custom ASCII art or text to appear as the header in the application. For example, a user might want their header to look like this:

```
  __  __           _      
 |  \/  |         | |     
 | \  / | ___   __| | ___ 
 | |\/| |/ _ \ / _` |/ _ \
 | |  | | (_) | (_| |  __/
 |_|  |_|\___/ \__,_|\___|

```
This would be ideal for blog owners, developers, or enthusiasts who want to personalize their application interface.

---
**Proposed Solution**

1. Add a configuration option where users can input their desired ASCII art or text to replace the default header.
2. Validate the input to ensure it fits within a reasonable width and does not break the layout.
3. Provide a fallback to the default header in case the input is invalid or left empty.

---
**Benefits**

- Enables users to express creativity and individuality in their application interface.

- Makes the application more appealing and customizable.

- Enhances the user experience by catering to a broader range of preferences.

---
**Additional Context**

If needed, we can provide examples or templates for ASCII art that users can easily modify to create their own headers. Additionally, we could include an option to preview the header before applying it.

---
**Potential Challenges**

- Ensuring compatibility with various screen sizes and layouts.
- 
- Preventing invalid or overly large input from disrupting the application's appearance.
