• [x] I have searched existing requests and this feature hasn't been requested yet
• [x] This is a single feature request (not multiple features)

Problem Statement

Currently, the input text box is fixed at the bottom of the terminal. When working with long hours, I find myself fixated on the bottom left corner of the screen for a long time. Having the input at the top would make my neck feel much better!

Proposed Solution

Add a configuration option to allow users to choose the placement of the input box

• bottom (default)
• top

Alternative Solutions

Using tmux to rearrange panes, but this adds complexity.

Priority

Low - Nice to have
