Feature suggestion: mode-specific themes

Created by: SableRaf

Description

It would be great if each mode had its own unique theme, chosen from the list of themes available. This could be a user-defined setting in the theme selector, where they can apply the theme to the current mode they're using. This way, users could easily distinguish between modes at a glance. Alternatively, we could allow mode creators to include a custom theme in their mode.

Expected Behavior

A way to make the modes stand out even more, by allowing each mode to have its own theme from the available options.

Current Behavior

Currently, modes do not have the ability to have their own distinct theme.

Steps to Reproduce

1. Open the PDE
2. Switch to another Mode
3. Observe that all modes use the same theme

Your Environment

• Processing version: 4.1.2
• Operating System and OS version: Windows 10

Possible Causes / Solutions

• The current theme system does not have the capability for modes to have their own distinct theme, a feature enhancement to include this functionality would be needed.

Start by tracing the PDE theme selector and mode-switching behavior described in the issue. Determine whether user-defined themes or themes supplied by mode creators should be supported, then verify that switching modes applies the selected distinct theme while preserving the existing theme options.
