Note on XML Export

The manual "Export Theme XML" operator has been retained intentionally. This operator does not implement custom XML serialization — it wraps Blender's own rna_xml.rna2xml function, which is the same serializer Blender uses internally for theme presets. The operator simply provides a convenient file browser dialog so users can choose where to save the file.

What was removed in this revision:

• Automatic XML export to config/themes/ on every theme apply (the export_xml preference)
• The XML snapshot mechanism used for theme reset
• The custom ITERM_OT_reset_theme operator (replaced by Blender's built-in preferences.reset_default_theme)

The add-on no longer writes to any Blender config directories. All theme changes are made exclusively through the Python API (bpy.context.preferences.themes[0]), and the only file I/O is the manual export which is user-initiated via a file browser.

If the preference is to remove this operator entirely and defer to Blender's built-in theme preset save, I'm happy to do so — just let me know.

Changelog (v1.1.4)

Module Reload

• Replaced sys.modules loop with the official _needs_reload = "bpy" in locals() reload pattern.

XML Auto-Export Removed

• Removed automatic XML export to config/themes/ on theme apply.
• Removed export_xml preference toggle.
• Removed _snapshot_current_theme() function and all snapshot references.
• Retained manual export operator (uses Blender's native rna2xml serializer with a file browser).

Reset Operator Removed

• Removed ITERM_OT_reset_theme operator entirely.
• "Reset" button in the UI now calls Blender's built-in preferences.reset_default_theme.

UIList Fix

• Removed self.layout_type property check from ITERM_UL_theme_list.draw_item (removed in Blender 5.0 API).

Cache Path Simplified

• get_cache_dir() now uses bpy.utils.extension_path_user() exclusively with no fallback paths.

Blender 5.0 Theme API Support

• Added _is_5 = bpy.app.version >= (5, 0, 0) runtime detection.
• Version-branched all per-editor properties removed in 5.0 behind if not _is_5 guards:
  • panelcolors (header, back, sub_back)
  • navigation_bar, tab_active, tab_inactive, tab_back, tab_outline
  • frame_current (per-editor)
  • channels_region, dopesheet_channel, dopesheet_subchannel
  • channel_group, active_channels_group
  • All per-editor keyframe colors
  • All per-editor handle colors
  • time_scrub_background, time_marker_line, time_marker_line_selected
• Added complete 5.0 unified theme mappings:
  • theme.regions.sidebars — background, tab background
  • theme.regions.channels — background, text, selected text
  • theme.regions.scrubbing — background, timestamp text, markers
  • theme.regions.asset_shelf — header, background
  • theme.common.anim — playhead, preview range, channels, keyframes (all types), long keys
  • theme.common.curves — all handle types (free, auto, vector, align, auto-clamped, vertex)
  • theme.user_interface — panel_active, panel_outline, editor_outline, editor_outline_active
• Version-branched renamed 3D Viewport properties:
  • edge_seam → seam, edge_sharp → sharp, edge_crease → crease
  • edge_bevel + vertex_bevel → bevel (combined)
  • freestyle_edge_mark + freestyle_face_mark → freestyle (combined)
• Per-editor asset shelf guarded behind if not _is_5 (moved to theme.regions.asset_shelf).

Dual Version Support

• Single codebase supports both Blender 4.5 LTS and 5.0+ via runtime version branching.
• Note, support for 4.5LTS will be removed when version 5.2LTS is released.
• Existing _try_set() helper provides additional graceful degradation for any edge cases.
