+- **alwaysFilter**: Sets if the custom filter (text filed at the top right) is maintained or if it's reset when new messages are emitted.
 - **autoDemangle**: Automatically filters the new messages with [ddemangle](https://github.com/dlang/tools#d-tools). Note that Coedit uses the tool as a daemon so it's perfectly normal that it remains in the task list when the IDE runs.
 - **autoSelect**: Defines if the widget change dynamically the message categories.
 This is a recommended setting because if a run-time error happens, it will be immediately displayed.
