Input field font ignores IDE Editor font settings

[flobo3]

Problem

The prompt input field uses a default monospace font (Courier-like) that cannot be customized. This is inconsistent with the rest of the IDE and the chat output area, which respects the configured Editor font.

The Appearance → Fonts settings only allow overriding font size for chat messages and code blocks, but:

1. The input field is not affected by these settings at all
2. There is no way to change the font family anywhere in the plugin
3. The input field doesn't inherit the IDE's Editor font setting

Suggested fix

The most natural approach: inherit the input field font from the IDE's Editor font (Settings → Editor → Font), just like the chat output already does. This requires zero new config options.

If more control is desired, the Appearance → Fonts tab could be extended with:

• Font family override (not just size) for both chat text and input field
• A dedicated "Input field font" section

Environment

• DevoxxGenie plugin v0.4.23+
• IntelliJ IDEA 2025.x
• Islands theme (reproduced with default themes too)

Update: root cause found in source code

After looking at the code, this is more of a bug than a feature request.

CommandAutoCompleteTextField (extends JBTextArea) never sets a font — so it falls back to the Swing default (Courier/monospace).

Meanwhile, FontUtil already reads the IDE Editor font correctly:

EditorColorsScheme scheme = editorColorsManager.getGlobalScheme();
float fontSize = scheme.getEditorFontSize();

But FontUtil is never referenced from PromptInputArea or CommandAutoCompleteTextField. The utility exists but the input field doesn't use it.

Minimal fix — in PromptInputArea constructor, after creating the CommandAutoCompleteTextField:

inputField = new CommandAutoCompleteTextField(project);
// Apply IDE Editor font to input field
EditorColorsScheme scheme = EditorColorsManager.getInstance().getGlobalScheme();
Font editorFont = scheme.getFont(EditorFontType.PLAIN);
inputField.setFont(editorFont);

This would also need a SettingsChangeListener to update the font when the user changes IDE Editor font settings.

For the font family specifically, FontUtil currently only reads fontSize but not the font family from the scheme. scheme.getFont(EditorFontType.PLAIN) would give both family and size.
