Feature Description

It would be nice to be able configure the colours used in the launcher (and preferably also being able to export/import those preferences).

Could be related to #180 in terms of the configuration.

Problem Statement

You can't currently customise the colours of the launcher.

Proposed Solution

Being able to change the colour of UI elements through the settings window (i.e. bg and fg text colour, border colour, bg colour, etc.)

It would be nice to be able to configure/import and export these colours using TOML or JSONC

Use Cases

Consistency for users who like to use a colour scheme for their system and programs, or just anyone who wants to change the colours I guess.
