# Features

## Dialog system

The dialog system has been overhauled for better extensibility.

The `SimpleDialog` class now allows to create a custom dialog.

`ProgressDialog` is a dialog that displays progress (duh!) inspired by Github for Windows.

For reference, see PR #[785](https://github.com/MahApps/MahApps.Metro/pull/785)

# Fixes

- Fixed high GPU usage when the `MetroProgressbar` is hidden.

[#812](https://github.com/MahApps/MahApps.Metro/issues/812)

- Fixed the window glow not hiding when the window is hidden
