                        <li> - Added hotkeys <kbd>1</kbd>-<kbd>9</kbd> to set brush size quickly </li>

                        <li> - Can be applied on erasing and painting now </li>
                    </ul>
                </li>
                <li>New Marching Cube Export <kbd>Export->mc</kbd>: export your voxel model as Marching Cube meshes (<kbd>.ply</kbd>) </li>
                <li>Camera Control: use middle button to move camera </li>
                <li>Cache Folder <kbd>cache/</kbd>: program will automatically backup model before quitting program or rendering model </li>
                <li>Obj Export Pivot: fixed bugs for obj pivot, you can also set your custom pivot in <kbd>config.txt->file_obj</kbd> </li>
                <li>Palette Command: added command <kbd>pal mask</kbd> to mask out unused color in palette </li>
                <li>Fixed a little rendering bug with orth/iso camera, still not very robust though </li>
