- replace old PopupMenu (flat preset list) with PopupPanel-based menu - add 3-icon toolbar: ⚙ Settings, ℹ Info, ✕ Remove (+) + Add - red ✕ on tiles removes the tile; green + on empty space opens add-tile submenu - 'Themes ▸' button opens a submenu with all ShaderPresets - add-tile submenu populates from PluginManager.get_all_tile_defs() - all toolbar buttons are 48×48 flat buttons with 24px font for touch - orphan PopupPanel children cleaned up during grid rebuild
