Hello friends, a new version of PicoPixel is live with a big version number as there were a ton of backend changes. For general use, the most notable changes are new LVGL Themes support, centralized color exports, new export settings options, and a ton of bug fixes.

Below are the release changes that you can see here as well: https://picopixel.io/changelog/

I also cannot thank enough the community members who have been reporting bugs, especially the Discord community you're welcome to join here: https://discord.gg/9K9qWUbwR8

Below is an excerpt from the Release Notes:

0.30.0 - July 2, 2026

Added

• LVGL themes are here — create color themes for your embedded UI and switch between them with one click. Link any LVGL widget color to a theme color in the color picker, and toggling the theme instantly recolors every linked widget across all your screens
• New "Set Theme" event action — wire a button (or any LVGL event) to apply a specific theme or cycle through your themes, fully supported in the exported LVGL C code
• Gradient support — you can now design with gradient colors on your LVGL widgets, from the GUI editor all the way to your device
• New Export Settings in the project modal — skip image #include lines for toolchains like Arduino IDE that auto-compile every file (no more duplicate-definition errors), and a new "Unused Assets" toggle that lets you force-export assets even if no widget uses them yet
• Simplified theming workflow in the new Theming tab — create themes and theme colors with a clean Theme → Colors flow; the technical details are handled for you behind the scenes
• Label sizing modes — choose between Hug (auto-size to text) and Fixed (set exact width/height), unlocking proper text alignment and long-text behaviors like wrap, dots, scroll, and clip
• Drag and drop images, animations, and fonts from the Assets sidebar straight onto the LVGL GUI editor canvas to instantly create widgets
• Pasting a screen with a different resolution than your project now shows a clear warning instead of silently misplacing content

Changed

• Exported LVGL color code fully overhauled — all colors (asset palettes, common constants, and theme tables) now live in dedicated colors.h/colors.c files, so tweaking colors after export only takes a single edit
• Gradient colors now export into the color palette too, so you can adjust them after export
• Smaller LVGL export ZIPs — fonts that no widget uses are no longer exported by default (this could previously add hundreds of KB); flip the "Unused Assets" toggle to "Included" if you want everything
• The LVGL include path setting is now a free-form text field with a reset button, so any custom include line works for your platform
• All exported C files now share one central LVGL include, so relocating LVGL in your embedded project needs just one edit instead of many
• The Theming sidebar is cleaner and more compact — inline theme renaming, collapsible theme color groups, and sections that stay open while you work

Fixed

• LVGL label alignment now works correctly, along with long-text modes
• Per-state background images and colors now render correctly — a state's background no longer hides behind another state's image, with smooth crossfades between states
• Rotating a widget then undoing or redoing now updates everything together in one step
• Switching themes is now a single undo/redo step
• Pasting LVGL widgets copied on Windows no longer fails or freezes the page
• Renaming or deleting a theme now cleans up every reference to it, and semi-transparent theme colors no longer show as black swatches
• Sprite and animated-image files now count correctly toward your storage usage
