Release v0.25.0

• Fill widget - horizontal battery layout now fills the whole cell instead of shrinking and leaving empty margins in short/wide widgets
• Fill widget - bar width/height now previews live while editing instead of only after leaving the field
• Input widget - add field alignment (left / center / right) to position a fixed-width input field within its cell
• Layout menu - configurable spacing: gap between the layout list and the element above it, space above/below the menu title, and space above/below each added element (clock / datapoint / text)
• 🌟 New feature: Group widget - add "collapsed by default" option: the group shows only its header and folds its body away until clicked to expand (frontend only)
