OATControl V1.2.0.0 Release

Custom Theme Engine

OATControl now has a completely custom theming system. The MahApps.Metro dependency has been fully removed and replaced with a purpose-built theme engine that gives you full control over the application's appearance.

Built-in Themes

• Dark Astronomy — the classic dark red theme, now the default
• Daylight — a new light theme with blue accents, ideal for daytime use
• Blue Planet, Dark Observatory, Deep Space, NINA — additional themes bundled with the installer

Switch themes instantly from Settings > General > Theme. Your selection is saved and restored on the next launch.

Theme Editor

A full visual theme editor lets you create and customize your own themes:

• Live preview shows your changes on a miniature app window in real time
• Interactive color picker with HSL saturation/lightness square, hue bar, and RGB/HSL sliders
• Hex input for precise color entry
• Grouped color keys organized by category (text, backgrounds, buttons, borders, etc.)
• Save and share your themes as files — import themes from other users or export your creations

Open the theme editor from Settings > General > Edit Themes.

Smaller Installer

The installer no longer includes the MahApps.Metro and ControlzEx libraries. This reduces the number of deployed DLLs and simplifies the application dependency chain.

Other Improvements

• All dialogs and windows now use a unified custom window chrome with consistent styling
• Slew progress bars for RA, DEC, and drift alignment have been consolidated into a reusable control
• Toggle switches, buttons, and other controls have been restyled for consistent theme support

• Removed the unused Step Calibration dialog
• Replaced System.Windows.Forms file dialogs with native WPF equivalents
